An adaptor plug for a spin-on fluid filter, in particular for a spin-on return filter, wherein the adaptor plug comprises a plug-in end which is designed to be plugged into a cavity in a flange of a hydraulic device in a fluid tight manner and a filter end which is designed to be connected to the spin-on filter in a fluid tight, detachable manner and at least one internal fluid channel connecting said plug-in end with said filter end, wherein the adaptor plug at its filter end comprises a threaded tube or bolt on which the spin-on filter can be screwed. By this design, the use of a filter set with or without an adaptor ring between the adaptor plug and the filter is enabled. By the adaptor plug, the spin-on filter can be applied to a variety of hydraulic devices, among others, with a 16 UNF cavity.

A self-cleaning mechanism for a pneumatic central clutch release includes: a release piston which is coaxially arranged around a hollow shaft and is mounted such that it moves in the direction of an axis of the hollow shaft; and a housing which at least partially surrounds the release piston so as to form a pressure chamber between the hollow shaft, the housing and the release piston, which is sealed from the environment and can be connected to a fluid pressure source; and a cleaning chamber fluidically arranged between the pressure chamber and the environment. The cleaning chamber is able to be connected to the environment by way of a ventilation channel.

An oil supply system for a vehicle includes a plurality of oil pumps, suction oil passages, and a communication passage. The oil pumps are independently operational. The suction oil passages each connect an associated one of suction portions of the plurality of oil pumps and a common oil strainer. The communication passage connects the suction oil passages.

A throttle assembly for a pressure control system in a vehicle includes at least one throttle valve. The at least one throttle valve defines an assembly cross-section of the throttle assembly, the assembly cross-section specifies a flow resistance acting on a pressure medium entering the throttle assembly, and the at least one throttle valve includes at least one controllable throttle valve configured to be controlled in accordance with an upstream pressure. The assembly cross-section of the throttle assembly is configured to be set, by control of the at least one controllable throttle valve, in such a way that an inlet volume flow of the pressure medium entering the throttle assembly can be limited to a limit volume flow in accordance with the upstream pressure, in order to set, in accordance with the upstream pressure, a power consumption of a pneumatic load in the pressure control system.

The present disclosure relates to a nozzle assembly for a servo valve. The nozzle assembly comprises a nozzle including a nozzle inlet and a nozzle outlet, and a tubular filter mounted to the nozzle for filtering fluid flowing into the nozzle through the nozzle inlet.
