Abstract
The invention is based on an apparatus (10) for regulating the pressure in a hydraulic circuit that comprises an electrically triggerable pressure-control valve (12), a receptacle device (14) in which the pressure-control valve (12) is installed, and means (54, 64) for damping pressure pulsations. In order to save space, simplify the manufacture of the receptacle device (14), and save additional holding elements, it is proposed according to the invention that the means (54, 64) for damping pressure pulsations be designed as integral components of the pressure-control valve (12).
Claims10
An apparatus (10) for regulating the pressure in a hydraulic circuit having an electrically triggerable pressure-control valve (12) that comprises a solenoid part (16) having an electrically triggerable coil (20), a moveably guided armature (22) and a hydraulic part (18) coupled to the solenoid part (16), in which a shutoff element (32) able to be acted upon by the armature (22) controls the flow of hydraulic fluid between at least one working passage (48) and a return passage (46), and having means (54, 64) for damping pressure pulsations in the working passage (48), wherein the means (54, 64) are an integral component of the pressure-control valve (12) and, in interaction with its housing, limit at least one pressure chamber (64) located on the circumference and having a variable volume.
