Abstract

The invention relates to the technical field of motor vehicle hydraulic braking systems and provides a plunger type booster pump. The pump comprises oil inlet screws (1), a pump body (2), a different diameter plunger (3), seal rings (4), oil seals (5), a spring (6) and a spring base (7); when the braking oil pressure is lower in the stage of eliminating braking gap of the braking beginning of a motor vehicle, the output oil pressure Po is equal to the input oil pressure Pi, and after the braking gap is eliminated, when the input oil pressure Pi rises in the stage of braking working, the output oil pressure Po is higher than the input oil pressure Pi; the formula of the output oil pressure is shown in the description, wherein D is the large end diameter of the different diameter plunger (3), and d is the small end diameter of the different diameter plunger (3). The plunger type booster pump is simple in structure, convenient to process, small in size, low in cost and safe and reliable, saves energy, and can achieve boost effect under the condition that energy such as compressed air or vacuum source is not needed.

Description

technical field [0001] The invention relates to the technical field of motor vehicle hydraulic brakes, in particular to a plunger type booster pump. Background technique [0002] At present, the booster pump widely used in motor vehicle hydraulic braking devices needs to use compressed air or vacuum sources to achieve the boost effect. When the power system fails, there are potential safety hazards and insufficient energy consumption due to the decrease in supercharging effect. Contents of the invention [0003] In order to overcome the above disadvantages, the present invention provides a plunger type booster pump that realizes the boost effect without using energy such as compressed air or a vacuum source, and has a simple structure, low cost, safety, reliability, and energy saving. [0004] The technical solution adopted by the present invention to solve the technical problem is: a plunger type booster pump, including oil inlet screw (1), pump body (2), different diame...
