The invention relates to a valve for controlling volumetric flows in a heating and/or cooling system of a motor vehicle, comprising a valve housing (), from which at least one inlet channel () and at least one outlet channel () branch, in addition to at least one disc-type valve body () for controlling the flow, said body being located in the valve housing so that it can rotate about the axis () of a driven shaft (). According to the invention, the valve body () is operatively connected to an electromotive drive () by means of a gear system (). The invention also relates to a heating and/or cooling system () of a motor vehicle, comprising a valve () of this type.

Valve for controlling volumetric flows

A drive device for a part of a vehicle that can be adjusted between terminal positions, in particular the roof panel of a vehicle roof, having an electric motor that is connected to a pinion via a first step-down gear. A switch device that controls the electric motor for stopping the electric motor in at least one predetermined position of the adjustable part, and a second step-down gear that moves a switch body. A magnetic-field-sensitive sensor, controllable by the switch body, for controlling the switch device. A conductor track board inside a housing and extending with an extension over the path of motion of the switch element. The magnetic-field-sensitive sensor is disposed at a radial distance from the circular path of motion of the switch body and bridges the distance between the magnetic-field-sensitive sensor and the path of motion of the switch body by means of magnetic flux guide bodies. The magnetic flux guide bodies can be produced inexpensively of soft magnetic wire so that the conductor track board can be made with straight boundary edges, oriented at right angles to one another, in order to avoid waste.

Drive device for adjusting a device between terminal positions

A brush holder equipped as a component on a printed circuit board and is inserted into a recess provided in a transmission housing of the drive device and thereby can be slid in the radial direction over a commutator of an already completely assembled armature. The drive device according to the invention is provided for moving a sliding sunroof of a vehicle.
