Problems solved by technology

[0004] (1) The operator must open the air release bolt, turn the cab forward or move the seat, etc., to press the manual oil pump, which increases the labor intensity and difficulty
[0005] (2) In the process of manual emptying, the fuel is directly discharged out of the car along with the air, causing waste and pollution

Embodiment Construction

[0018] Refer to attached figure 1 , the thrust generating device is composed of: sealing cap (1), housing (2), starting coil (3), push body (4), stroke coil (5), inner sleeve (6), spool (7), traction Spring (8), bracket (9), air groove (10), travel switch (11), pressing table (12) are used to generate the thrust of the vehicle manual fuel pump; adjust the position of the thrust generating device and the manual fuel pump, Make the pushing body (4) contact with the manual fuel pump accordingly, when the starting coil (3) is energized, the spool (7) will start to move downward under the action of the electromagnetic force generated by the starting coil (3). After the spool (7) moves for a certain stroke, press the table (12) to make the stroke switch (11) fixed on the bracket (9) act, thereby turning on the power supply of the stroke coil (5) and cutting off the power supply of the starting coil (3). Power supply, because the start coil (3) and stroke coil (5) adopt a certain po...

Abstract

The invention discloses an automatic automotive diesel engine fuel pipe intake air exhaust mechanism, which comprises a pushing force generator, an exhaust switch, a contactor, a fuel-recovering pipe, a relay and an electromagnetic valve. The pushing force generator is used for generating pushing force; after the air enters an automotive diesel engine fuel pipe, when a manual fuel pump needs to be pressed to exhaust the air, the relay can close according to a certain cycle as long as the exhaust switch is pressed, as a result, by controlling the contactor, the pushing force generator can automatically press the manual fuel pump according to a certain cycle until the air is completely exhausted, and consequently, the labor difficulty and intensity of an operator in manual exhaust is eliminated; since the electromagnetic valve is used for substituting for the conventional bleed screw of the diesel engine fuel pipe, during exhaust, not only can the air be effectively exhausted, but also fuel can be conveniently recovered by the fuel-recovering pipe mounted on the electromagnetic valve, and thereby waste and pollution are prevented.

Description

technical field [0001] The invention relates to an automatic emptying mechanism after the fuel pipe of a diesel engine for a vehicle takes in air. Background technique [0002] After the fuel pipe of the vehicle diesel engine is air-intake, the diesel engine cannot be started, and the vehicle cannot run. Therefore, the air in the fuel pipe must be emptied. For this reason, the vehicle diesel engine is specially provided with a manual fuel delivery pump. Although the manual fuel pumps of diesel engines currently produced can be emptied by pressing directly, when it needs to be emptied, the operator must manually operate, and first turn the cab forward, or move the seat, etc. If the operator Inexperienced, this process has to be repeated many times to start the vehicle; moreover, the operator has to open the vent bolt before pressing the manual fuel pump. When the manual fuel pump is pressed to a certain extent, the fuel will be released from the vent bolt Expelled directly w...
