Abstract
Disclosed is a pressure control device including a housing incorporating a pressure control valve which governs a connection between a pressure-fluid inlet and a pressure-fluid outlet. Included is a deceleration-responsively movable inertia member, and control piston arranged in the housing and being slidable in dependence upon the pressure of the pressure fluid and the position of the inertia member and acting upon the pressure control valve. In order to provide for a pressure control device which is more cost-efficient and which switches precisely irrespective of the viscosity and the flow velocity of the pressure fluid, the inertia member is arranged in a chamber of the pressure control device which is substantially free from pressure fluid and the inertia member controls a valve which isolates a compartment confined by the housing and the control pisotn from the chamber.
