Abstract: 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 ¾ 16 UNF cavity.

Abstract: A combined valve for insertion into an elongated bore of a power unit body of a hydraulic power unit may have an elongated carrier for receiving a relief and a check valve. The valve may also have a register arranged at a first axial position of a longitudinal axis of the carrier for calibration of the relief valve. The valve may also have a check valve coupled to the carrier at a second axial position along the longitudinal axis of the carrier. The valve may also have a relief valve coupled to the carrier at a third axial position along the longitudinal axis of the carrier. A minimal distance between the first and the second axial position may be less than a minimal distance between the first and the third axial position.
