ABSTRACT:
A pressure control device, preferably for use in a control system of an automatic transmission of a motor vehicle, comprises a housing which accommodates a magnetic coil and an armature, and a control slide actuated by the armature and movable within a valve through which pressure medium to be controlled passes. A plunger carrying the armature is arranged coaxially to the magnetic coil within the housing and is supported at the both ends axially. A diaphragm spring is arranged at the end of the plunger facing toward the control slide. A pin loaded with the control pressure and arranged at the end of the control slide opposite to that facing the plunger acts on the control slide. A compression spring provided on the armature develops a force which acts against the force of the electric magnet and the hydraulic force which acts on the pin. The pressure control device is therefor suitable for controlling of considerably higher pressures and greater volumes of the pressure medium.
