    Abstract: The present disclosure relates to a valve assembly, in particular for use in a tire inflation system, the valve assembly comprising: a valve body comprising a first fluid port and a second fluid port; a piston disposed at least partially within the valve body and configured to be moved relative to the valve body between an open position and a closed position, wherein when the piston is in the open position the first fluid port is fluidly connected with the second fluid port, and wherein when the piston is in the closed position the first fluid port is fluidly isolated from the second fluid port, wherein when the piston is in the open position the first fluid port and the second fluid port are fluidly connected with one another via a fluid channel extending through the piston. The present disclosure further relates to a tire inflation system including said valve assembly.

    Abstract: A swash plate bearing is disclosed. The swash plate bearing may have an arcuate cage member having at least one flange and a plurality of rolling elements rotatably coupled to the at least one flange. A coupling seat extends laterally from the at least one flange, the coupling seat may have an insertion hole. A link member may be rotatably coupled to the cage member, the link member having a central portion positioned between a first terminal portion and a second terminal portion. A first stem connects the central portion to the first terminal portion and a second stem connects the central portion to the second terminal portion. The central portion is positioned in the insertion hole.

    Abstract: A piston hydraulic device comprises a cylinder block having a plurality of cylinder assemblies and is rotatable about a first rotation axis. Each cylinder assembly comprises a cylinder and a piston. A port plate has a first port and a second port that are angularly spaced relative to the first rotation axis. A plurality of first conduits connect respective cylinders alternately to the first port or the second port. At least one second conduit is connected to a fluid reservoir. At least one directional control valve is positioned in the first conduit and fluidly connects to the second conduit. The at least one directional control valve connects the cylinder to the port plate in a first position and to the fluid reservoir in a second position. A controller is operatively associated with the directional control valve for switching between the first and the second positions.

    Abstract: The present document relates to a hydraulic system having a first hydraulic pump, a second hydraulic pump, at least one hydraulic actuator, a low-pressure tank, and a pressure controlled flow compensating valve. A high-pressure port of the first hydraulic pump and a high-pressure port of the second hydraulic pump are fluidly connected or fluidly connectable to the at least one hydraulic actuator. The high-pressure port of the second hydraulic pump is selectively fluidly connectable to the low-pressure tank via the flow compensating valve. The flow compensating valve is controllable by or based on one or more of: a hydraulic pressure provided by the first hydraulic pump, a hydraulic pressure provided by the second hydraulic pump, and a hydraulic pressure at a fluid port of the at least one hydraulic actuator.
