  • Patent number: 10865891
    Abstract: A control piston (12) is longitudinally displaceable in a housing (10) having two connection points (P, A) for fluid, and cooperates with a metering edge (34) of the housing (10) at a connection point (P). Point (P), in control positions of the control piston (12), supplies the connection point (A) with fluid via a fluid connection. The piston, as a result of occurring flow forces, tends to be drawn in the direction of a closing position that blocks one of these fluid connections. To compensate the flow force, the control piston (12) has, in the region of the control edge (34) of the housing (10), a shape modification (48) of its cylindrical exterior basic form (50), such that a flow contact surface (52) for fluid is created. The contact surface transfers a compensating force that acts against the flow force to the control piston (12) and that seeks to pull the control piston (12) into an opening position opposed to the closing position.

  • Patent number: 10421443
    Abstract: A solenoid valve comprises a valve closing body, which can open or close a valve passage formed in a valve seat body which is pressed into a valve housing, and comprising a magnet armature acted upon by a restoring spring, arranged in a through-bore of the valve housing. In addition to a press-fit segment, the valve seat body has a clearance-fit segment along the outer jacket of the valve seat body. The clearance-fit segment has a reduced outside diameter in relation to the press-fit segment. The valve housing also has a tube segment, which deflects radially inward and which has a constant inside diameter that is reduced relative to the outside diameter of the press-fit segment. The tube segment thus deflecting into the clearance-fit segment of the valve seat body because of the elasticity of the tube segment.

  • Patent number: 10408362
    Abstract: A flow control valve includes a valve body having an bore and a plurality of fluid ports in communication with the bore. A valve spool is axially slidably disposed in the valve body, and an end portion of an end of the valve spool has a convex curved surface. A linear actuator is disposed at one end of the valve body and includes an armature slidable along an axial direction of the valve spool. The armature includes a head portion having a convex curved surface configured to abut against the end portion of the valve spool. The engagement structure between the valve spool and the armature of the flow control valve is improved, which enables the valve spool and the armature to be automatically aligned. This reduces the precision requirement of contact between the valve spool and armature, which facilitates mass production and reduces cost of the valves.
