Abstract: An electromagnetic valve for a hydraulic system for an automatic transmission of a vehicle. An armature chamber is filled with hydraulic medium and fluidically connected to hydraulic lines of the hydraulic system. An armature is mounted in the armature chamber such that its stroke is adjustable. The armature includes a shut-off body and divides the armature chamber into an opening-side chamber facing the flow opening and into an inner chamber facing away from the flow opening. During a stroke of the armature, an oil exchange occurs, and a displacement volume of the hydraulic medium overflows from the opening-side chamber into the inner chamber. A hydraulic line leading to the opening-side chamber or to the inner chamber of the armature chamber includes a dirt collecting element that is designed as a permanent magnet and that retains contaminations in the hydraulic medium that flows through the hydraulic line during an oil exchange.

Abstract: A pilot valve system is controlled by the pressure differential between a lower chamber and an upper chamber. A fluid passageway in the lower chamber fluidly connects an inlet to first and second outlets. By varying the pressure differential, the placement of a stem within the fluid passageway is varied so fluid can flow between the inlet and only one of the first and second outlets at a time. Pressure in the lower chamber can be varied by using a second fluid to exert pressure against a bottom end of the stem. Pressure in the upper chamber is varied by using an adjusting screw to urge a spring against the diaphragm.
