Abstract

The utility model discloses a cylinder structure of an air booster pump, which comprises a cylinder body. An air inlet is arranged on a sealing side of the cylinder body, a connecting cover is installed at the position of a cavity opening of the cylinder body, a push rod is slidably installed in the connecting cover, a central seal ring is sleeved on the push rod, a push rod piston is installed at the rod end of the push rod located in the cylinder body, a return spring is connected between the push rod piston and the connecting cover, and a seal ring is sleeved outside the push rod piston. The cylinder structure of the air booster pump is simple and easy to achieve, and the working stability of both the cylinder and the air booster pump is effectively improved.

Description

The air cylinder structure of air booster pump
Technical field
The utility model relates to the auto parts machinery field, is specially a kind of air cylinder structure of air booster pump.
Background technique
The air booster pump is the vitals in the running gas circuit braking system, and its effect is through fuel delivery in the atmospheric pressure Control of Automobile oil circuit, to realize the running braking.Existing technology air booster pump comprises cylinder and hydraulic cylinder, and wherein the cylinder long-term work is corroded in the fluid environment easily, causes job insecurity, influences the normal use of air booster pump.
The model utility content
The utility model purpose provides a kind of air cylinder structure of air booster pump, to solve existing technology air booster pump cylinder operation problem of unstable.
In order to achieve the above object, the technological scheme that the utility model adopted is:
The air cylinder structure of air booster pump comprises the cylinder block with inner chamber, it is characterized in that: said cylinder block is one side closed; Opposite side is the inner chamber accent; And the cylinder block closed side is provided with the suction port that is communicated with the cylinder block inner chamber, and said cylinder block accent place is equipped with connecting cover, is slidingly fitted with the push rod that stretches in the cylinder block in the said connecting cover; Be arranged in and be with the central seal circle that constitutes sealing with connecting cover on the push rod of connecting cover; The rod end that said push rod is arranged in cylinder block is equipped with push-rod piston, is connected with return spring between said push-rod piston and the connecting cover, and push-rod piston is with the seal ring that constitutes sealing with the cylinder block sidewall outward.
The air cylinder structure of described a kind of air booster pump is characterized in that: said cylinder block accent edge is provided with mounting platform, and said connecting cover is connected with cylinder block through bolt, also through bolt link press span is arranged on the mounting platform of cylinder block accent.
The utility model is simple in structure, is easy to realize, the connecting cover of sealing cylinder cylinder body is installed in the cylinder block accent; Push rod is installed in the connecting cover; And through being installed in central seal circle and the sealing of connecting cover formation in the connecting cover, avoided the central seal circle to contact with fluid and corroded, the push-rod piston of push rod installation simultaneously is through seal ring and the sealing of cylinder block formation; Can effectively improve the sealing of cylinder block, return spring can be guaranteed the timely return of push rod.The utility model has effectively improved the working stability of cylinder and air booster pump.
