Telescopic pipe assembly for a hydraulic power unit. The telescopic pipe assembly includes, in one example, a first pipe including multiple indents or recesses that are positioned along a portion of the first pipe and a second pipe including an alignment opening, where the first pipe is axially moveable in relation to the second pipe and where the alignment opening is configured to align with each of the multiple indents or recesses in multiple axial positions. The telescopic pipe assembly further includes an attachment device configured to extend through the alignment opening and user-selectably mate with one of the multiple indents or recesses to fix an axial position of the first pipe in relation to the second pipe.

Telescopic pipe assembly

The present document relates to a control device for a central tire inflation system, comprising: an inlet for connection with a pressure source, at least a first outlet for connection with a first pneumatic tire, a supply valve, at least a first channel valve, and at least a first pressure-limiting valve, wherein the supply valve and the first channel valve selectively fluidly connect the inlet to the first outlet and are fluidly connected in series between the inlet and the first outlet, and wherein the first pressure-limiting valve is fluidly connected to the first outlet for limiting a pressure at the first outlet. The present document further relates to methods of operating the control device for the central tire inflation system.

Control device, tire inflation system including said control device, and methods of operating said tire inflation system

A system is disclosed including an electric motor having a rotor shaft, a hydraulic pump including a gear; and an end bell housing enclosing an end of the electric motor, the end housing having a plurality of cooling fins, the end housing further supporting the gear coupled to the rotor shaft, the gear pressurizing hydraulic fluid.

Electric motor with integrated pump

A fluid filter device with a housing defining a cavity, the housing including a fluid inlet and a fluid outlet, a filter unit including a filter substrate and arranged within the cavity such that the filter unit and the housing define, within the cavity, a first chamber in fluid communication with the fluid inlet and a second chamber in fluid communication with the fluid outlet. The filter unit is movable relative to the housing between a first position and a second position such that in the first position, the first chamber is in fluid communication with the second chamber through the filter substrate, and in the second position, the inlet is in fluid communication with the outlet through a bypass line.

Fluid filter device

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 &#xbe; 16 UNF cavity.

Adaptor plug for a spin-on filter

A hydraulic system, comprising: a hydraulic pump, a hydraulic load, and an electric machine. The electric machine working as an electric generator and mechanically coupled with said hydraulic pump. A low-pressure fluid tank and a valve assembly comprising one or more valves selectively fluidly connecting the hydraulic load with the low-pressure fluid tank.

Hydraulic system with energy recovery

The present disclosure relates to a fluid power pack, comprising: a manifold block comprising at least one fluid port; a first housing mounted on the manifold block and enclosing a first tank configured to hold a liquid; an electric motor mounted on the manifold block and disposed within the first tank so that the electric motor is configured to be submerged in a liquid held within the first tank for cooling the electric motor; a second housing mounted on the manifold block and enclosing a second tank configured to hold a liquid; and a hydraulic pump mounted on the manifold block and drivingly engaged with the electric motor, the hydraulic pump comprising a low pressure port and a high pressure port. The high pressure port of the hydraulic pump is in fluid communication with the fluid port of the manifold block and the low pressure port of the hydraulic pump is in fluid communication with the second tank. The present disclosure further relates to a hydraulic system including the fluid power pack and a hydraulic load fluidly connected with the fluid power pack.
