Engine that converts the potential energy of a liquid fluid stored in its upper tank to kinetic energy

Abstract

The present invention is applicable in mechanical engineering. The invention introduces an engine propelled by weights difference acting on its Piston heads (31). The Mechanism of the said engine is able to turn any size of a generator to produce electricity, since the power of the engine can be increased by increasing the height of the Upper Tank (1) or by increasing the number of Piston (10) or by increasing the diameter of the Piston (10) while the used liquid fluid which is described as "the liquid fluid with a small load" in the detailed description is the by-product of the mechanism and is limited to the size of the Piston Cylinder (32). Thus for example the mechanism can turn a 10 Mega Watt generator when an Upper Tank (1) is placed at a height of 30 meters and two Inlet Pipes (3) of 86 millimetres in diameter are connected to a two piston engine that has two Piston Cylinders (32) of 500 cc (cubic centimetres) each, thus for every 180° (degrees) turn of the generator only half a litre of the used liquid fluid is produced as a by-product, thus allowing the used liquid fluid to be recycled back to an Upper Tank (1) using a small high speed domestic / agricultural electric, petrol or diesel Water Pump (5).

Description

[0001] PATENT DESCRIPTION

[0002] Title: Engine that converts the potential energy of a liquid fluid stored in its upper tank to Kinetic energy.

[0003] Technical Field

[0004] The present invention relates to mechanical engineering, and more particularly of an engine that converts the potential energy of a liquid fluid stored in its upper tank to kinetic energy that can be used to generate unlimited amounts of electricity and also propel very large cargo ships or warships.

[0005] BACKGROUND OF THE INVENTION

[0006] This present invention is a correction and improvements of patent no KE913 of 2021 owned by Mwendwa Mwongela. The title of the invention is also changed from “Engine propelled by weight difference acting on its piston heads” to “Engine that converts the potential energy of a liquid fluid stored in its upper tank to kinetic energy". The improvement includes adding a method of limiting the speed of its revolving cranksharft, replacing a mechanical Two-way Valve with a Two-way Solenoid Valve and also replacing a conveyor belt for recycling its used liquid fluid with an electric pump. Thus also doing away with a camshaft, timing chain, timing gear and crankshaft gear of the previous engine patented with the above mentioned patent number. The correction involves a claim 2 of the above mentioned patent which states “The engine according to claim 1, characterized in that the said engine has Pistons that operate in pairs and are set at 180°(degrees) apart from each other thus when one Piston is at the top of its Piston cylinder the other Piston of the same pair is at the bottom of its Piston cylinder and due to weight difference acting on the two Piston heads of the same pair, a Piston at the top of its Piston cylinder is pushed downwards while a Piston at the bottom of its Piston cylinder is push upwards causing a crankshaft assembly to turn by 180°(degrees)”. This is an error since a piston on its downwards motion will land on its Bottom dead center point if turned by only 180° (degrees) while the other piston of its same pair on its upwards motion will also land on its Top dead center point if turned by only 180° (degrees), where the applied force is straight along the axis of its crankshaft assembly and its two pistons, meaning no turning force can be applied. This is particularly with a two piston engine. Thus the claim as it is, is faulty. In reality a crankshaft assembly with good working roller bearings is caused to turn by almost 270° (degrees). Thus the claim 2 should have be written as “The engine according to claim 1, characterized in that its said engine has Pistons that operate in pairs and are set at 180°(degrees) apart from each other thus when one Piston is at the top of its Piston cylinder its other Piston of the same pair is at the bottom of its Piston cylinder and due to weight difference acting on both Piston heads of the same pair, a Piston at the top of its Piston cylinder is pushed downwards while a Piston at the bottom of its Piston cylinder is push upwards causing a crankshaft assembly to turn by more than 180°(degrees)”.

[0007] Also important to note is that it is impossible for a crankshaft assembly with good working roller bearings to turn by exactly 180° (degrees) unless something causes it.

[0008] SUMMARY OF INVENTION

[0009] The present invention describes an engine that converts potential energy of a liquid fluid stored on its upper tank to kinetic energy. The invention further teaches of a pair of Two-way solenoid valves that allow liquid fluid with a big load to act on one piston while also allowing liquid fluid with a small load to act on the other piston of the same pair. The invention further teaches that the pair of Two-way solenoid valves are able to switch the weight difference of the two pistons after every 180°(degrees). Due to the weight difference acting on the two pistons, the pistons are able to maintain a reciprocating motion.

[0010] The invention further describes a Crankshaft assembly that is designed to convert the reciprocating motion of its Pistons to useful circular motion that can be connected to a generator to generate unlimited amounts of electricity.

[0011] The invention further teaches of a way of limiting the speed of its revolving Crankshaft Assembly.

[0012] The invention also describes a method of recycling the used liquid fluid using an electric, petrol or diesel pump. Brief Description of the Drawings

[0030] DETAILED DESCRIPTION OF THE INVENTION

[0031] Now turning to the detailed description of the invention according to Figs. 1,2, & 3 represents an overview of the engine as described in the present invention. Availing an engine that converts the potential energy of a liquid fluid stored in its Upper Tank (1) to Kinetic energy. Its Pistons (10) operate in pairs and are set at 180° (degrees) apart. Thus when one Piston (10) of the same pair is at the top of its Piston cylinder (32) the other Piston (10) of the same pair is exactly at the bottom of its Piston cylinder (32). Liquid fluid bearing a big load from an upper tank (1) enters its Piston cylinder (32) through its Two-way Solenoid Valve (4) and hits a Piston Head (31) of its Piston (10) at the top of its Piston cylinder (32) perpendicularly thus pushing the Piston (10) downwards. While its other Piston (10) of the same pair is at the bottom of its Piston cylinder (32), liquid fluid bearing a smaller load acts on its Piston head (31) is pushed upwards due to its smaller load.

[0032] In a similar embodiment, the invention provides that as a Piston (10) bearing a big load reaches the bottom of its Piston cylinder (32) a designed mechanism allows liquid fluid bearing a small load to now act on its Piston head (31), while its other Piston (10) of the same pair bearing a small load reaches the top of its Piston cylinder (32) a design mechanism allows liquid fluid bearing a big load to now act on its Piston head (31) and push it downwards. Due to weight difference acting on the two Piston heads (31) of the two Pistons (10) that operate in pairs, its Pistons (10) are able to maintain a reciprocating motion. Pistons (10) are pinned to Connecting rods (33) by Piston pins (39). A Connecting rod (33) is firmly bolted to a Con-rod pin (50) of a Crankshaft assembly (8) by a Con-rod bearing cap (34). Thus a Crankshaft assembly (8) converts the reciprocating motion of its Pistons (10) to usefully circular motion. At the front of the Crankshaft Assembly (8) is the Front main bearing pin (35) that can be connected to a generator to generate unlimited amounts of electricity. A 360° (degrees) movement of both pairs of pistons (40 &41) in a four-cylinder engine is illustrated in Figs 12 a, b, c, d, & e. Where in Fig 12 (a) the pairs of pistons (40 &41) are at 0° (degrees), while in fig 12 (b) the pistons pairs (40 &41) have turned by 90° (degrees) and in fig 12(c) the pitons pairs (40 &41) have turned by 180° (degrees) and in fig 12(d) the pistons pairs (40 &41) have turned by 270° (degrees)and in fig 12 (e) the pistons pairs (40 &41) have turned by 360° (degrees) and are back again at 0° (degrees). Where also in the Fig 12 a, b, c, d & e, the reference number (29) refer to a First Way (29) of the Two-way Solenoid Valve (4). A way which allows liquid fluid with a big load to act on the Piston Head (31) and push it downwards. While reference number (30) refer to the Second Way (30) of the Two-way Solenoid Valve (4). A way which allows liquid with a small load to act on the Piston Head (31) at the bottom of its Piston Cylinder (32) and is pushed upwards. While reference numbers (52) and (53) refer to the two pairs of throws of the Crankshaft Assembly (8) where in each pair the throws are set at 180°(degrees) apart.

[0033] In another embodiment according to Fig. 4, 5, 6 & 7 the present invention teaches of a case of a four-piston engine. The engine has four ‘Two-way Solenoid Valves’ (4) that are each connected at the top of each Piston cylinder (32). A Two-way Solenoid Valve (4) according to Figs 8, 9 & 10 consists of the following: a. A Two-way Solenoid Valve (4) has three openings. One at the top (11) that connects it to its Inlet Pipe (3) that is from an Upper Tank (1), another one at the side (12) that allows its used liquid fluid to pass through it and pour into an Exhaust Manifold (57) and one at the bottom (14) that connect it to its piston cylinder (32) as the Two-way Solenoid Valve (4) is bolted to its engine block (7) by bolts (22). b. At the top of a Two-way Solenoid Valve (4) is a Solenoid Coil (15) that pulls and pushes a Sliding Gate (16) that allows the flow of liquid fluid with a big load from an Upper Tank (1) to pass through it and act on its Piston Head (31) when its Sliding Gate (16) is opened and when its Sliding Gate (16) is shut stops the flow of liquid with a big load from passing through it as it simultaneously allows the used liquid fluid with a small load to be expelled from its Piston Cylinder (32). c. At the side of a Two-way Solenoid Valve (4) is a Solenoid Coil (17) that pulls and pushes a Sliding Gate (18) that allows the flow of the used liquid fluid with a small load from the bottom of its Piston Cylinder (32) to be expelled from its Piston Cylinder (32) and into an Exhaust Manifold (57) when the Sliding Gate (18) is opened. When the Sliding Gate (18) is shut, liquid fluid with a big load is allowed to pass through it and act on its Piston Head (31). d. A solenoid coil (15) at the top of its Two-way Solenoid Valve (4) has two cables that are each connected to a Sensor Switch (25 & 26). One cable (25) connects an upper Sensor Switch (24) that Triggers its Solenoid Coil (15) to pull its Sliding Gate (16) to open when the Piston Head (31) of its Piston (10) contacts the Top dead center point of it Piston Cylinder (32). Its other cable (26) connects a lower Sensor Switch (23) that Triggers its Solenoid Coil (15) to push its Sliding Gate (16) to close when the Piston Head (31) of its Piston (10) contacts the Bottom dead center point of its Piston Cylinder (32). e. A Solenoid Coil (17) at the side of its Two-way Solenoid Valve (4) has two cables (27 & 28) that are each connected to a Sensor Switch (21 & 20). One cable (27) connects an upper Sensor Switch (21) that Triggers its Solenoid Coil (17) to push its Sliding Gate (18) to close when the Piston Head (31) of its Piston (10) contacts the Top dead center point of it Piston Cylinder (32). Its other cable (28) connects a lower Sensor Switch (20) that Triggers its solenoid coil (17) to pull its Sliding Gate (18) to open when the Piston Head (31) of its Piston (10) contacts the Bottom dead center point of its Piston Cylinder (32). f. Both Solenoid coils (15 & 17) of a Two-way Solenoid Valve (4), share an Electric Cable (19) that connects them to the main electricity.

[0034] In another embodiment according to Figs 6, 7, 8 & 9 the invention teaches of a “First way (29)” of a Two-way Solenoid Valve (4) that allows liquid fluid with a big load to pass through it and act on the Piston head (31) of a Piston (10) at the top of its Piston cylinder (32) and push it downwards. This First way(29) occurs when an upper Sensor Switch (24) of the top Solenoid Coil (15) triggers its Sliding Gate (16) to open when a Piston Head (31) of a piston (10) contacts the top dead center point of its Piston Cylinder (32). While at the same time simultaneously an upper Sensor Switch (21) of the side Solenoid Coil (17) triggers its Sliding Gate (18) to close when a Piston Head (31) contacts the top dead center point of its Piston Cylinder (32).These two simultaneous actions causes a Two-way Solenoid Valve (4) to be opened in the first way (29). Thus causing a Piston (10) at the top of its Piston cylinder (32) to be push it downwards and as it reaches the bottom dead center point of its Piston Cylinder (32), a “Second way (30)” of a Two-way Solenoid Valve (4) is opened. This Second way (30) and according to Fig 6, 7 & 10 allows the used liquid fluid which bears a small load to be expelled from its Piston Cylinder (32) as the Piston (10) is now on its upward motion. This is caused to happen when a lower Sensor Switch (23) of the top Solenoid Coil (15) triggers its Sliding Gate (16) to close when its Piston head (31) contacts the bottom dead center point of its Piston Cylinder (32). While at the same time simultaneously a lower Sensor Switch (20) of the side Solenoid Coil (17) triggers its Sliding Gate (18) to open when a Piston Head (31) contacts its bottom dead center point of its Piston Cylinder (32). These two simultaneous actions cause a Two-way Solenoid Valve (4) to be opened in a second way (30). Thus causing a Piston (10) at the bottom of its Piston cylinder (32) to be pushed upward and as it reaches the top dead center point of its Piston Cylinder (32), a First way (29) is again opened. Thus enabling the piston to maintain a reciprocating motion. In another embodiment according to Fig. 6 & 7 the invention avails that there are four “Two- way Solenoid Valves” (4) in a four piston engine, each Two-way Solenoid Valve (4) serving one Piston (10). These four, Two-way Solenoid Valves (4) operate in pairs. In each pair when one Two-way Solenoid Valve (4) is opened in the First way (29), the other Two-way Solenoid Valve (4) of the same pair is opened in the Second way (30). The first pair is called the First Pair of Two Way Solenoid Valve (37) while the next pair is call the Second pair of Two Way Solenoid Valve (38). Pistons (10) of these two Two-way Solenoid Valves (4) also operate in pairs. The pistons (10) are set at 180° (degrees) apart by the structure of the Crankshaft Assembly (8) and also operate in pairs the first pair is called First pair of Piston (40) while the next is called Second Pair of Piston (41). Thus a piston (10) at the top of its piston cylinder (32) has its Two-way Solenoid Valve (4) opened in a First way (29) to allow liquid fluid with a big load to act on its piston head (31) and push it downwards and as it reaches the bottom dead center of its piston cylinder a design mechanism allows liquid fluid with a small load to now act on it. The other piston (10) of the same pair is at the bottom of its piston cylinder (32) has its Two-way Solenoid Valve (4) opened in a Second way (30) to allow it’s used liquid fluid with a small load to be expelled from it piston cylinder (32) as its piston (10) is pushed upward due to its small load and as it reaches the top dead center of it Piston Cylinder (32) a design mechanism allows liquid fluid with a big load to now act on it. Thus the pairs of the piston (40 & 41) are able to maintain the reciprocating motion that its Crankshaft Assembly (8) is able to convert to useful circular motion.

[0035] Yet in another embodiment according to Fig. 13a and 13b the invention teaches that, liquid fluid with a big load from an Upper tank (1) enters a piston cylinder (32) through its Inlet pipes

[0036] (3) as it passes through its Two-way Solenoid Valve (4), when its Two-way Solenoid Valve

[0037] (4) is opened in a First way (29) and hit its Piston Head (31) of a piston (10) at the top of its piston cylinder (32) perpendicularly with a big load pushing the piston (10) downwards. This liquid fluid with a big load from above is prevented from sipping through the piston (10) and into the Engine block (7) by a set of two Piston rings (42) that are inserted into the Compression ring grooves (43) of the Piston (10). While according to Fig. 13c and 13d Rubber or Plastic seals (61) placed at the brim of the Piston Head (31) can also be used to prevent the liquid fluid with a big load from sipping through the piston (10) and into the Engine block (7). To prevent the wearing of the Piston (10) against the Piston cylinder (32) the Piston (10) has an Oil ring (44) inserted into the Oil ring groove (45) of the Piston (10) that has drilled holes that allow oil to pass through and lubricate the Piston (10) together with the Piston cylinder (32). These drilled holes are linked to a network of oil passages inside the Engine block (7) that originate from the oil pump.

[0038] In another embodiment according to Fig. Ila the invention avails that the Crankshaft Assembly (8) of a four-cylinder engine consists of the following parts. i. Eight Arms (46). ii. Four Con-rod pins (50). iii. Front Main pin (35). iv. Back Main pin (48). v. Mid Main pin (36). vi. Two Intermediate Main pins (51) vii. Nine Roller Bearings (49)

[0039] According to Fig 11c a Crankshaft Assembly (8) has four Throws (47) each attached to one Piston (10). A Throw (47) consist of two Arms (46), a Con-rod pin (50) and a Roller Bearing (49). The Throws (47) of the Crankshaft Assembly (8) operate in pairs (52 & 53). In each pair of Throws (47), the Throws (47) are set at 180°(degrees) apart and this also allows the pairs of pistons (40 &41) to also be set at 180°(degrees) apart. Thus according to Figs 11b and lid in a four-cylinder engine there are two pairs of throws (52 and 53). The two pairs are then rotated from each other by an angle of 90°(degrees) due to the shape of the mid Main pin (36). The front Main pin (35) of the Crankshaft Assembly (8) is shaped to allow for the connection of a generator so as to allow for the generation of electricity and can also be connected to the propeller of a very big cargo ship or war ship so as to propel the ship.

[0040] In another embodiment according to Fig 4a, 4b, 14a & 14b the present invention teaches of a case of a Speed Sensor (54) that monitors the speed of a rotating Crankshaft Assembly (8). This Speed Sensor (54) is mounted on top of the Front Main pin (35) of the Crankshaft Assembly (8) and as the speed of a Crankshaft Assembly (8) reaches a certain point this Speed Sensor (54) triggers a Solenoid Coil (55) to shut a Throttle Valve (56). This action causes the used liquid fluid in an Exhaust Manifold (57) to stop draining into a Eower Tank (6) and start accumulating along a Vertical Pipe (58) and as the volume of the used fluid continues to increase in a Vertical Pipe (58), the weight difference acting on the two pairs of piston (40 &41) continues to diminish. This causes the rotation of the Crankshaft Assembly (8) to slow down. As the rotation of the Crankshaft Assembly (8) slows down to a certain point the Speed Sensor (54) trigger the Solenoid Coil (55) to now open the Throttle Valve (56). This action allows the used liquid fluid which had accumulated inside the Exhaust Manifold (57) and the Vertical Pipe (58) to now drain into the Lower Tank (6). Thus the crankshaft Assembly (8) is able to maintain a constant speed of a certain range. Cable (59) connects a Speed Sensor (54) to the Solenoid Coil (55) while a steel cable (60) links the Solenoid Coil (55) to the Throttle Valve (56).

[0041] In another embodiment according to Figs. 1, 2 & 3 the invention avails that, as the Piston (10) begins it is upwards motion to start to expel its used liquid fluid which bears a smaller load inside its Piston cylinder (32). This used liquid fluid which bears a smaller load is then expelled through the side opening (12) of its Two Way Solenoid Valve (4) and enters into an Exhaust Manifold (57) and then drains into a Lower Tank (6). An Electric, Petrol or Diesel Pump (5) recycles the used liquid fluid by sucking it through a Suction Pipe (9) from a Lower Tank (6) then pumps the liquid fluid via its Delivery Pipe (2) back into its Upper Tank (1).

[0042] It is important to note that the force that drives a Crankshaft assembly(8) around is the weight difference of its two Pistons heads(31) that operate in pairs and it is due to this fact that the weight of liquid fluid acting perpendicularly at the top of a Piston head (31) on its downwards motion is greater than the weight of liquid fluid acting on the top of its other Piston head(31) of the same pair on its upward motion to begin expelling its used liquid fluid from its Piston cylinder(32) and into its Exhaust Manifold (57)and then pours into a Lower Tank (6). Thus the force that drives a Crankshaft assembly (8) around is the force of Gravity.
