Abstract
The present invention relates to a braking pressure control device for automotive vehicles including a regulating valve, composed of a regulating piston (5) and a valve closure member (6), which governs the connection between a pressure-fluid inlet (3) and a pressure-fluid outlet (4). The valve closure member (6) is coupled to a pressure-responsive displaceable control piston (20). The control device also includes a deceleration responsive deflectable inertia member (33). The displacement of the control piston (20) is controlled as a function of the position of the inertia member. In order to simply accomplish an abrupt and temperature-independent locking of the control piston when a deceleration value is exceeded, the inertia member (33) moves into a mechanical latching engagement with the control piston (20).
