摘要： 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.

摘要： A clutch transmission, in particular a dual clutch transmission, includes a hydraulic circuit for actuating and/or cooling the clutch transmission. The hydraulic circuit includes at least one cooler for cooling a hydraulic medium conveyed by at least one pump, wherein a bypass with a thermostatic bypass valve is associated with the cooler. The thermostatic bypass valve has hereby three switching positions, wherein it can be moved to a first switching position by a spring force, from the first switching position to the second switching position by a thermal element against the spring force and from the second switching position to a third switching position against the spring force by a pressure difference exceeding a predeterminable limit value.
