Embodiment Construction

[0011] Below, will refer to figure 1 , the booster compressor of the present invention will be described.

[0012] In the upper part of the crankcase 1, a discharge check valve 4 is provided in the top wall 3 of the cylinder 2, and above the top wall 3, a discharge chamber 6 with a discharge hole 5 is provided.

[0013] In the crankcase 1, a drive shaft 8 is rotatably mounted via bearings 9, 9 and seals 10, which is integrally connected with the crankshaft 7 and driven by a suitable power source. The piston rod 12 is rotatably connected to the crankshaft 7 via a bearing 11 at one end, and is rotatably connected to the piston 13 in the cylinder 2 at the other end.

[0014] A gas guide groove 14 is formed on the inner periphery of the cylinder 2 . When the piston 13 is at the lowest position, the lower end of the gas guiding groove 14 communicates with the inside of the crankcase 1 , and the upper end of the gas guiding groove 14 communicates with the space above the piston 1...

Abstract

A compressed gas is introduced into a casing. A piston pivotally connected to a reciprocating mechanism moves up and down in a cylinder. The compressed gas in the casing is sent to a space on the piston through a groove formed in the inner circumference of the cylinder and is further compressed in the space by the piston.

Description

technical field [0001] The invention relates to a booster compressor which uses a reciprocating piston to compress compressed gas. Background technique [0002] exist figure 2 shows a conventional booster compressor in which a suction check valve 23 is formed on one side of a top wall 22 of a cylinder 21 and a discharge check valve 24 is formed on the other side of the top wall 22 . A suction chamber 26 having an inlet 25 and a discharge chamber 28 having an outlet 27 are formed above the suction check valve 23 and the discharge check valve 24, respectively. A crankshaft 31 is arranged in the crankcase 29 below the cylinder 21, and the crankshaft is connected as a whole with a drive shaft 30 driven by an external power source. A piston 33 in the cylinder 21 is reciprocated by a crankshaft 31 by a piston rod 32 . Via the suction check valve 23, the N 2 Such compressed gas is introduced into the space above the piston 33 , compressed, and then discharged via the discharge ...
