Patent Searching and Data


Title:
【発明の名称】圧力変動を減衰する装置
Document Type and Number:
Japanese Patent JP2944715
Kind Code:
B2
Abstract:
The vehicle brake system has a master brake cylinder to generate brake pressure in at least one wheel brake. To avoid wheel locking during braking, a pressure control valve assembly and a pump for drawing pressure fluid out of the wheel brake are disposed between the master brake cylinder and the wheel brake. With its outlet, the pump communicates with the master brake cylinder via a damper chamber and a throttle having a pressure limiting valve disposed to bypass the throttle. The throttle and the pressure limiting valve have a common sleevelike housing, in which a cylindrically embodiment closing element is guided longitudinally movably. This closing element has a hollow collar on its face end that in the closing position fits over an inflow opening for pressure fluid. The collar of the closing element, in order to form the throttle, is provided with at least one aperture open toward this face end. The pressure limiting valve, which responds if the throttle is blocked with particles, overcomes the cross-sectional limitation of the throttle, so that the throttle can be self cleaning.
