A hydraulic valve system has a valve housing, which has a first connection side and a second connection side. The valve housing has a through-hole for accommodating at least one piston. The valve housing has a third connection side with at least three hydraulic connections which are each connected to the through-hole via a line. The hydraulic valve system has a connection block with at least three hydraulic through-lines each extending from a first connection opening arranged on a housing side of the connection block to at least one second connection opening arranged on a hole pattern side opposite the housing side. Each of the at least three first connection openings is connected in a fluid-tight manner to one of the at least three hydraulic connections, and the second connection openings are arranged in a pre-defined hole pattern. A method for manufacturing a valve housing is also disclosed.

An example control valve includes a split valve body. The split valve body includes a first body portion, a second body portion, a flow path, an inlet port, and an outlet port. The flow path passes through the first body portion and the second body portion. The first body portion is coupled to the second body portion. The control valve also includes a valve seat. The valve seat is disposed between the first body portion and the second body portion. The control valve also includes a valve plug. The valve plug is movable relative to the valve seat to control fluid flow through the control valve.

A vehicle stabilization system including a frame; a wheel; a control arm connected to the frame and the wheel; a fluid spring connected to the frame and the control arm; a stabilizer connected to the frame and operable between a retracted and extended position; a reservoir; and a fluid manifold connected to the fluid spring and the chamber, fluidly coupling the spring interior and stabilizer chamber to the reservoir interior. A vehicle stabilization method including maintaining an orientation of the vehicle frame, coupling the frame to a support surface using a stabilizer by introducing a fluid to a chamber of the stabilizer, and retracting a wheel by reducing a quantity of fluid within a fluid spring coupling the wheel to the frame.

A module includes a parallelepiped main body having four lateral faces extending between an upper face and a lower face, in which an inner chamber is provided in the main body, opening in the top and bottom faces in order to receive, on the inside, a distribution or regulation device. The inner chamber includes, consecutively, an upper bore, an intermediate bore that has a smaller diameter than the upper bore, and a lower bore that has a smaller diameter than the intermediate bore. A plate is provided on each lateral face for attachment to a plate of a similar adjacent module, the plate having peripheral holes used for the passage of attachment screws and a central blind hole suitable for guiding a drill hole opening in the upper bore or in the intermediate bore.

A valve device includes a relief valve configured to be opened when a pressure in a fluid pressure circuit reaches a predetermined pressure and to relieve a working fluid, a tank passage connected to a tank, a main relief passage connecting the relief valve and the tank passage, and a sub relief passage branching from the main relief passage and connected to the tank passage separately from the main relief passage.
