Abstract: The application relates to a rotary valve, in particular a multi-way regulating valve, with a housing, which has at least one inlet connection and at least one outlet connection for a liquid and/or gaseous medium, with at least one valve element, which is rotatably mounted in the housing between the connections in order to set at least one desired flow cross-section, and with a control shaft, which is non-rotatably connected to the valve element, which control shaft is led out of the housing with a coupling end, through an opening in a housing wall of the housing, wherein the control shaft has a radial projection, which has an axial stop for making axial contact with an annular sealing protrusion of the housing wall, and with at least one sealing element acting between the control shaft and the housing.

Abstract: The application relates to a valve device, in particular for a cooling water system of a motor vehicle, comprising a housing, which has an inflow connection and a first outflow connection and a second outflow connection, and comprising a valve, which is mounted in the housing so as to shift in the axial direction, said valve having a cylindrical main part, at each end of which a valve element is arranged in order to close one of the connections in a first sliding end position of the valve and another one of the connections in a second sliding end position of the valve, and having a first spring element, which biases the valve in the direction of the first sliding end position, and having a thermally activatable actuator element, which is designed to push the valve against the force of the spring element, in the direction of the second sliding end position, upon being activated.

Abstract: A valve device for a cooling water system of a motor vehicle, with a housing including a first connection and a second connection for a first liquid circuit, and a third connection and a fourth connection for a second liquid circuit, wherein the first connection is permanently fluidically connected to the second connection, and with a valve unit including a movably mounted valve element with which a thermally activatable spring element is associated, and which opens a connection between the third connection and the fourth connection in a first end position and cuts off the connection in a second end position. The thermally activatable spring element is arranged in a chamber located between the first connection and the second connection, which is permanently cut off from the third and the fourth connection and which preloads the valve element in the direction of the second end position.

Abstract: The application relates to a valve device, including a valve housing which has at least three connection openings, each of which open into a chamber of the valve device, including two sealing disc units arranged at a distance from each other, each of which lies between two adjacent chambers and has a fixed sealing disc and at least one rotatable sealing disc, wherein each of the rotatable sealing discs and the fixed sealing discs of each sealing disc unit has at least one throughflow opening in order, in at least one overlapping position of the throughflow openings, to release a throughflow cross-section between the adjacent chambers, and including an actuating shaft, which is connected to the rotatable sealing discs for conjoint rotation.

Abstract: A disc valve, in particular a multi-way control valve, is provided which has a housing that has an inlet connection and an outlet connection as connections for a liquid and/or gaseous medium. The connections end in respectively different chambers of the housing, at least one valve disc, in particular a ceramic valve disc, which is provided with at least one first through-flow opening and is arranged rotatably mounted in the housing in order to fluidically connect and separate from each other the different chambers depending on its rotational position by means of the through-flow opening, and a control shaft, which is connected torque-proof to the valve disc in the housing. The disc valve is characterized in that the control shaft or the valve disc has a radial projection, and the housing has at least one rotation stop, which is located in the movement path of the radial projection.
