Abstract

The present invention relates to a pressure pump which is used for reducing the pulse in a vehicle slippage control system. The pressure pump comprises the components of a hollow bush which is fixed on the casing of the pump and a plunger piston that is supported by the internal spring in the bush. The pressure pump also comprises a valve ball which is used for blocking an outlet which is flowed by the working liquid that flows into the plunger piston, a one-way valve spring which is fixed at the outlet of the plunger piston and supports the valve ball, a one-way valve which is fixed on the cover on the plunger piston, a one-way valve outlet which comprises a valve ball and a one-way valve, and a hole component which is provided between the bush and the cap that is fixed at the end part of the bush. The hole piece is provided at a position which discharges the work liquid in the plunger piston to reduce the fluctuating pressure caused by the plunger piston that does reciprocating motion because of the eccentric wheel. Therefore, the fluctuating pressure generated in the pump can be reduced from 20 bar to 5 bar or less.

Description

technical field

[0001] The present invention relates to a pump for a vehicle slip control system, and more particularly, to a pressure-type pump with reduced pulsation. Background technique

[0002] Generally, vehicle brakes brake or decelerate a vehicle by transmitting brake pressure, which is hydraulic pressure, to wheel brakes based on operation of a brake pedal. As a moving vehicle is forced to a stop by the brakes, the vehicle skids due to brake pressure or road conditions during braking.

[0003] A type of brake that electronically controls the braking force on the wheel brakes and is widely used to prevent skidding from occurring. That is, the widespread use of anti-lock braking systems (ABS), traction control systems (TCS) to prevent large slippage of the drive wheels during quick starts or acceleration, or electronic stability program (ESP) systems to reduce the vehicle's ideal driving The difference between the direction and the actual direction of travel, so tha...
