Abstract
The utility model relates to a novel automobile hydraulic brake pump, in particular to an automobile hydraulic brake pump with an offset oil inlet, which comprises a cylinder body, a piston and a spring are arranged in the cylinder body, and the oil inlet is formed on the cylinder body. The automobile hydraulic brake pump is characterized in that the axial direction of the oil inlet and that of the cylinder body are perpendicular, and the oil inlet is positioned at a relatively high point at the top of the round cavity of the oil cylinder and is tangent to the round cavity; an inner cavity is arranged on the piston, a center valve is arranged in the inner cavity, a center valve rod is arranged at one end of the center valve and i arranged in the center hole of the piston, and a coniform spring is arranged at the other end of the center valve and pressed at the bottom of the inner cavity. The oil inlet is formed at a relatively high point at the top of the round cavity of the oil cylinder and is tangent to the round cavity, so as to conform to the current situations of the automobile layout.
Description
Technical field
This practicality is a kind of new automobile hydraulic braking pump, particularly a kind of hydraulic vehicle braking pump of the oil inlet direction of setovering.
Background technology
Existing hydraulic vehicle braking pump because that the oil inlet position is provided with is unreasonable, has influenced the layout of vehicle complete vehicle.
Summary of the invention
The purpose of this utility model is in order to adapt to the present situation that vehicle complete vehicle is arranged, to invent a kind of hydraulic vehicle braking pump that oil inlet is arranged at the biasing oil inlet direction of the high relatively point of cylinder body.
The purpose of this utility model is to realize by following form: the hydraulic vehicle braking pump of described biasing oil inlet direction, comprise cylinder body, be provided with piston and spring in the cylinder body, cylinder body is provided with oil inlet, it is characterized in that: oil inlet axially and cylinder body axially perpendicular, and oil inlet is positioned at the high relatively point at oil cylinder circular cavity top, and tangent with circular cavity.
One inner chamber is arranged on the described piston, be provided with central valve in the inner chamber, an end of central valve is provided with the center valve rod, and the center valve rod is located in the centre hole of piston, and the other end of central valve is provided with the taper spring, and the taper spring is pressed in the bottom of inner chamber.
Good effect of the present utility model is as follows: because oil inlet is a high relatively point of being located at the top of oil cylinder circular cavity, and tangent with circular cavity, so adapted to the present situation that vehicle complete vehicle is arranged.
