Abstract: 1. Device and valve for flow force compensation. 2. A device comprising at least one regulating piston (12), which is guided longitudinally movable in a housing (10) having at least two ports (A, P, T) for fluid, and which interacts with a control edge (56), following a step function, of the housing (10) at a pressure supply port (P), which supplies another port (A) serving as utility port in regulating positions of the regulating piston (12) with fluid, the pressure of which can be preset, via a fluid connection and thereby aims at pulling towards a closed position blocking this fluid connection due to occurring flow forces, wherein the regulating piston (12) has a change of shape (60) from its general outer basic shape in the area of the control edge (56) of the housing (10) for a flow force compensation such that a flow contact surface for fluid is provided, which causes a compensating force acting against the flow force to be introduced into the regulating piston (12), which force aims at pulling the regulating piston (12) into an open position opposite from the blocked position, is characterized in that the change of shape (60) also follows a step function, the function graph of which has at least one step more than the number of steps required to form the control edge (56).

Abstract: A proportional pressure regulating valve has a valve piston (12) longitudinally movable in a valve housing (10) and connecting a utility connection (A) to a pressure supply connection (P) or to a tank or return flow connection (T) dependent on the displacement position of the valve piston. The valve piston is actuated by an actuation magnet (48) that can be supplied with current. A control device (50) is between the valve piston (12) and the actuation magnet (48), and allows the valve piston (12) to become pressureless on the valve piston side (52) facing the actuation magnet (48). The valve piston (12) is displaced in the direction of the actuation magnet (48) under the supply and/or utility connection pressure when the actuation magnet is not actuated.

Abstract: A valve has a valve piston (12) guided longitudinally movably in a valve housing (10) and actuated by an operation device (14). In one valve piston position, a connection is produced between a pressure supply port (P) and a working port (A). In another valve piston position, a further fluid-conducting connection is produced between the working port (A) and a tank port (T). The pressure difference arising between the working port (A) and the tank port (T) as flow passes through the further fluid-conducting connection acts, by an actuation device (30), on the valve piston (12). The valve piston passes from a stop position (32), with the further fluid-conducting connection shut off, into a fully open opening position with an enlarged opening cross section from working port (A) to tank port (T).

Abstract: The invention relates to a valve device having a valve housing, and comprising a main piston (4) that is arranged in an axially slidable manner in a piston bore of the valve housing (2), via which a first consumer connection (A) and a second consumer connection (B) can be alternately connected to a pressure connection (P) and a tank connection (T1, T2) by way of the action of a first magnetic actuating system (6) and a second magnetic actuating system (8) and comprising two pilot pistons (14, 16). The invention is characterized in that in an actuated state of the respective pilot piston (14, 16), the main piston (4) follows the movement of said pilot piston (14, 16) due to the force ratio adjusting itself thereon, thus actuating the fluid-carrying connection between the pilot chamber (10, 12) of said pilot piston (14,16) and the assignable tank connection (T1, T2) such that pilot oil flows.

Abstract: A control device selectively fluidically connects and disconnects fluid connection points (A, P, T) by a valve (5), which controls fluid-conducting connection channels (55, 57, 59) extending between the connection points (A, P, T). The connection channels are arranged in a control block (3), into which the valve (5) is at least partially inserted. Proceeding from the respective fluid connection points (A, P, T), the connection channels (55, 59, 57) connected to the fluid connection points extend in parallel to each other until the connection channels lead into a respective control chamber (49; 53, 51). The valve (5) is retained in a receptacle (39) separating two adjacently arranged control chambers (49, 51) from each other.
