A non-return valve device has at least part of a flow channel for a fluid and a movable cord-like sealing element arranged in the flow channel. The sealing element is configured such that it can be moved at least partially between a closed position and an open position, wherein, in the open position, a fluid flow is permitted through the flow channel, whereas in the closed position, the fluid flow through the flow channel is blocked by form-fitting engagement with the sealing element.

A hydrostatic transmission pressure monitoring system includes a hydrostatic transmission and a pressure sensor data source. The hydrostatic transmission includes, in turn, a transmission casing, a pivoting yoke assembly rotatably mounted in the transmission casing, a hydrostatic pump-motor arrangement containing a hydraulic pump-motor circuit at least partially formed in the pivoting yoke assembly, and a pressure scaling device fluidly coupled to the hydraulic pump-motor circuit. The pressure scaling device is configured to generate a pressure-scaled output signal substantially proportional to a peak circuit pressure within the hydraulic pump-motor circuit. The pressure sensor data source is fluidly coupled to the pressure scaling device and is configured to generate pressure sensor data indicative of the pressure-scaled output signal.

A double 6-way valve for a vehicle cooling system provides various modes, reduces the number of parts of the cooling system, and improves packaging, compared to a conventional cooling system. The double 6-way valve includes: an upper housing including a plurality of upper nipples disposed at equal intervals on an outer circumference surface thereof; a lower housing stacked under the upper housing and including a plurality of lower nipples disposed at equal intervals on an outer circumference surface thereof; an upper hub rotatably mounted within the upper housing; a lower hub rotatably mounted within the lower housing and stacked under the upper hub; and a driving apparatus to rotate the upper hub and the lower hub.

A bicycle telescopic apparatus includes a first tube, a second tube, an actuating member, and a hydraulic positioning structure. The first tube defines an axial direction. The second tube is telescopically received in the first tube in the axial direction. The actuating member is movable relative to the first tube in the axial direction of the first tube. The actuating member is configured to move the second tube relative to the first tube in the axial direction. The hydraulic positioning structure is configured to position the first tube and the second tube relative to each other in the axial direction.

A multi-way valve for a motor vehicle, having a housing, in which a lower and upper chamber are disposed one above the other along an axis of rotation and are separated from each other by a separating wall. A lower valve body is disposed in the lower chamber for rotation about the axis of rotation. An upper valve body is disposed in the upper chamber for rotation about the axis of rotation. A drive shaft drives the lower and upper valve bodies. The drive shaft is torque-transmittingly connected to one of the two valve bodies and said valve body is torque-transmittingly connected to the other of the two valve bodies. A checking device checks for a correct alignment, and, in the event of an incorrect relative alignment of the two valve bodies in the peripheral direction, a reaction to the incorrect alignment can be automatically triggered.
