Abstract: An actuator housing for a valve apparatus for a coolant circuit of a motor vehicle includes an actuator housing part for receiving at least one actuator component. The actuator housing also includes a valve housing part for at least partially limiting and hydraulically sealing a region of a valve device to be hydraulically sealed.

Abstract: A valve apparatus is provided for controlling the flow of fluids in two temperature control circuits and includes an actuator, a valve housing with a first receiving chamber and a second receiving chamber, a direct ball valve having the first receiving chamber with at least a first and a second fluid port, wherein a first ball device with a first passageway is rotatably mounted in the first receiving chamber, wherein the first ball device is coupled to the actuator and is directly actuatable by the actuator, and an indirect ball valve having the second receiving chamber with at least a third and a fourth fluid port, wherein in the second receiving chamber a second ball device with a second passageway is rotatably mounted, wherein the second ball device is coupled to the first ball device and is thus actuatable by the direct ball valve and indirectly actuatable by the actuator.

Abstract: A skateboard axle assembly is described, having a connection plate for mounting the axle assembly to a skateboard deck and a wheel axle. The wheel axle has two ends, to each of which a wheel can be mounted. The wheel axle is movably coupled to the connection plate by two articulated arms. In addition, a skateboard having at least one skateboard axle assembly is described.

Abstract: A coolant circuit includes a first pipe segment, a second pipe segment, and a seal between the pipe segments which are displaceable relative to each other. A resilient locking tang runs parallel to the first pipe segment and has a detent element. An elongated guide portion runs parallel to and is spaced from the locking tang between the pipe segment and the locking tang. Spaced-apart arms run parallel to the second pipe segment beyond the end of this second pipe segment. An axially parallel web is configured between the arms and is fitted at its end facing the second sub-assembly with a detent shoulder which is engaged from behind by the resilient detent element when the pipe segments are plugged into each other. The resilient tang is received at a closed fit between the arms, and the elongated guide portion is guided by the arms.

Abstract: A valve fitted with a housing which comprises at least two mutually apart coolant hookups, and a thermally expansible device, including a housing and a push-rod and resting on the housing and operating in concert with a valve element that in turn operates in concert with an annular valve seat, said valve seat being situated between the two hookups, and a spring that biases the valve element toward the valve seat, wherein the valve element is in the form of an annular valve disk made by two-part injection molding, where one annular sealing portion is made of an elastomeric plastic and the remaining valve disk is made of a hard plastic, the outer sealing portion cooperating with the valve seat and the inner sealing portion cooperating in a sealing manner with a housing of the thermally expansible device.

Abstract: A premounted unit includes a pipe stub and a thermostatic valve. The pipe stub includes a valve seat mechanically biased by a valve spring against the valve seat and resting at its other end against a mating rest element. The unit further includes an expansible element which is configured between a segment of the pipe stub and the valve member and which opens the thermostatic valve as a function of temperature against the force of the valve spring. The unit further includes a U-shaped retention yoke of which the central strip rests against the mating rest element and the legs are connected to an annular cap element thereby recesses being constituted at mutually opposite sides at the inside of the annular cap element and the legs of the retention yoke being fitted at its ends with outwardly pointing hook elements that engage the recesses.

Abstract: A valve operating device defined by the following features: a slider supported in axially displaceable manner in a housing and linked by an actuation segment to the valve, a first biasing spring configured in the housing and pre-stressing the slider against a first stop, an expansible element configured in the housing and being displaceably supported in approximately coaxial manner relative to the slider between a second and a third stop, a second biasing spring acting on the expansible element and pre-stressing the element against the second stop, the configuration allowing cooperation between the expansible element's drive pin and the slider, a heater associated to the expansible element, a heat dissipating element associated with the expansible element and cooling the expansible element when latter rests against the third stop, the force exerted by the first biasing spring being larger than that of the second biasing spring.
