Abstract: A check valve includes an outer poppet therein having a central opening therein where the outer poppet is mounted on the internal lip within the body of a valve. The outer poppet is translatable relative to the inner lip and body and an inner poppet is mounted within the central opening of the outer poppet where the inner poppet is also translatable relative to the outer poppet and inner lip. A means for limiting the translation of the outer poppet relative to the internal lip and a means for limiting translation of the inner poppet relative to the internal lip allow the outer and inner poppet to extend between an open position and retracted position to allow improved flow area through the valve.

Abstract: The disclosure is directed to a valve arrangement for controlling a linear or rotary hydraulic motor. The valve is connected to a pump which acts as a pressure medium source by the valve means and to a tank. The tank connection may be either direct or indirect. The arrangement of the present invention includes at least one seat valve located in a main flow connection between the pump and a port of the motor. Each of the seat valves would adjust the flow in the main flow connection to the motor via a pilot flow adjustable by a pilot valve. The pilot flow originates from the main flow through the seat valve.

Abstract: An hydraulic valve of the flow-controlled type and including a valve housing provided with an inlet and an outlet and a valve body which is intended to coact with a valve seat in a manner to open and interrupt the connection between the inlet and outlet in dependence on a continuously controllable pilot flow in a pilot-flow channel extending from a pilot-flow chamber located on the side of the valve body remote from the valve seat to the outlet in the flow direction after the valve body. The pilot-flow chamber, in turn, communicates with the inlet via a variable constriction. For the purpose of simplifying this type of valve and rendering the valve more compact, the valve body is arranged in a recess which extends to the valve seat and which is formed concentrically with the valve seat. The recess is formed in a seat-part which incorporates one or more slots which are open towards the recess and which discharge into the pilot-flow chamber. The seat-part also includes at least one inlet port which communicates with the inlet and which also communicates with the slot or slots, such as to form the variable constriction, thereby providing a facility in which the valve body can be moved continuously between its valve-open and valve-closed positions in a controllable manner.

Abstract: Valve for pressurized media which includes a valve housing provided with inlet and outlet and a movable main valve plug for infinitely variably controlling the pressurized medium flow through the valve with the aid of a pilot flow originating from the pressurized medium flow and passing through a variable throttling means situated in the main valve plug. For obtaining a compact valve unit, the pilot flow control valve (18) is arranged in a member arranged as a lid on a cartridge sleeve including the valve housing, for opening or closing a pilot flow duct (15) in the cartridge in response to a control signal, a pressure compensation means (54) being arranged in the duct (15) after the throttling means (26) in the main valve plug (5) but before the pilot flow control valve (18), this means (54) being under the action of the pressure in the pilot flow duct (15) prevailing after the throttling means (26) and of a piston sensing the pressure in the valve inlet and/or outlet for throttling or interrupting the pilot flow before the pilot flow control valve (18) in response to pressure changes in the inlet or outlet.

Abstract: Pressure medium valve having a valve piston located in a valve housing for control of a main pressure medium flow through the valve by the aid of a pilot flow through a variable pilot flow restriction disposed in the valve piston, the pilot flow being derived from the main pressure medium flow and being controllable by means of a control pilot valve. To achieve temperature independent control without area increase in the pilot flow chambers, an additional restriction between the valve piston and the cylindrical wall surrounding the valve piston of the valve housing is incorporated. The additional restriction has the form of a peripheral clearance of a substantially greater axial length than height.

Abstract: A backflow assembly including a housing with a passage having at least one check valve positioned therein to permit fluid flow in one direction while preventing fluid flow in the reverse direction. The check valve includes a valve head connected to a stem having an outer surface. A hump extends radially outward from the outer surface of the stem. The stem is guided by a bushing during opening and closing of the valve. The bushing includes at least one retention member that moves along the outer surface of the stem during opening and closing of the valve. The interaction between the retention member and the hump on the outer surface of the stem causes a higher friction loss during opening and closing of the valve than other portions of the outer surface.
