ABSTRACT:
A known pressure control valve for vehicular hydraulic brake systems comprises a valve inserted between an inlet and an outlet with a control piston acting as a valve closure member and slidable in opposition to a spring force. The control piston cooperates with a sealing device encompassing the control piston, the sealing device carrying a valve seat and acting as a check valve from the outlet to the inlet. In accordance with the present invention the control piston is supported in an annular member which is axially slidable in a tubular member and a compression spring to provide the spring force is disposed outside the tubular member with at least one surface against which the compression spring abuts being adjustable during assembly.
