The invention provides a vehicle brake booster pump, and belongs to the technical field of brake pumps. The problem that an existing brake booster pump is large in size is solved. The vehicle brake booster pump comprises a pump body and a piston assembly, a cavity in the pump body is sequentially divided into an oil inlet cavity, an oil supplementing cavity and a brake cavity through the piston assembly, the piston assembly comprises a piston rod, a first communicating hole, a second communicating hole, a third communicating hole and a main cavity are formed in the piston rod, and an adjusting valve element and an elastic piece are arranged in the main cavity. The adjusting valve element separates the oil inlet cavity under the action of the elastic force of the elastic piece, the oil supplementing cavity and the braking cavity are communicated through the main cavity, the adjusting valve element can overcome the elastic force of the elastic piece to move under the action of oil pressure in the braking cavity, and the oil supplementing cavity is made to be communicated with the oil inlet cavity through the second communicating hole, the main cavity and the third communicating hole. The vehicle brake booster pump has the advantage that the volume of the brake booster pump cannot be increased under the condition that the brake effect is improved.
本发明提供了一种车辆制动增压泵,属于制动泵技术领域。它解决了现有的制动增压泵体积较大的问题。本车辆制动增压泵包括泵体和活塞组件,活塞组件将泵体内部的空腔依次分隔成进油腔、补油腔和制动腔,活塞组件包括活塞杆,活塞杆中具有第一连通孔、第二连通孔、第三连通孔和主腔室,主腔室中设有调节阀芯和弹性件,调节阀芯在弹性件弹力的作用下隔断进油腔、补油腔和制动腔通过主腔室相连通,调节阀芯能在制动腔中油压的作用下克服弹性件的弹力移动,使补油腔通过第二连通孔、主腔室、第三连通孔与进油腔相连通。本车辆制动增压泵具有在提升制动效果的情况下不会增大制动增压泵的体积的优点。
