Abstract: A pump device for a motor vehicle includes: a pump having a first pump member and a second pump member, the first and second pump members being movable relative to one another; an electric drive having a drive housing and an output shaft rotatable with respect to the drive housing; and a gear mechanism, which couples the output shaft to the first pump member and, by reversing a direction of rotation of the electric drive, is switchable between a first and an opposite second transmission ratio. The gear mechanism has: a planet stage having a planet carrier rotationally fixed relative to the drive housing, and/or first and second freewheels, oppositely directed with respect to one another, and which are arranged axially behind one another, and/or the second pump member has a drive shaft rotatable relative to the output shaft.

Abstract: In order to realize temperature control of a battery in a simplified manner, a control module having a coolant control valve, a coolant temperature sensor and a coolant pump is provided. The coolant control valve, the coolant temperature sensor and the coolant pump are integrally assembled to form the control module.

Abstract: A valve for mixing two gas streams, having a housing, a first gas inlet, a second gas inlet, and a gas outlet. The gas inlets are fluidically connected to the gas outlet. Downstream of the first gas inlet there is a guide element mounted displaceably inside the housing. By displacing the guide element, it is possible to control a flow cross section of a flow transfer opening for the transfer flow of the gas volume flowing in through the first gas inlet to the gas outlet through the guide element.
