Abstract: A discharge pressure scale (30) includes a valve housing (41) having a functional connector (A), a return flow connector (T) and a user connector (28). A valve piston (52) is guided such that it moves longitudinally against the effect of an energy accumulator (42), moving from a respective opening or regulating position, against a valve seat (94), into a closed position. The user connector (28) and return flow connectors (T) are separated from one another. The fluid pressure present at the user connector (28) can be guided onto a pressure-active surface (A1*) of the valve piston (52) by a pressure compensation device (70) in such a way that it moves into its respective opening or regulating position in a pressure-compensated manner due to the force of the energy accumulator (42).

Abstract: A pressure-regulating valve has a valve piston (10) subjected to the action of an energy store and guided longitudinally in a valve housing (12). The valve housing has a supply port (14), a utility port (16) and a tank port (18) actuated by a control part (20) closing with a sealing action. In connecting from the supply port to the utility port, a pressure reduction function is realized. In a fluidic connection from the utility port to the tank port, a pressure-limiting function is realized. The control part (20) has a control rod (22) with two control bodies (24, 26) spaced apart from one another. One control body (24) controls the connection between supply port (14) and utility port (16). The other control body (26) controls the connection between utility port (16) and tank port (18).

Abstract: The invention relates to a discharge pressure scale (30) consisting of at least one valve housing (41) having at least three fluid connection points in the form of a functional connector (A), a return flow connector (T) and a control connector (28), wherein a valve piston (52) is guided such that it moves longitudinally against the effect of an energy accumulator (42), moving from a respective opening or regulating position, against a valve seat (94), into a closed position, wherein the control (28) and return flow connectors (T) are separated from one another, characterised in that the fluid pressure present at the control connector (28) can be guided onto a pressure-active surface (A1*) of the valve piston (52) by means of a pressure compensation device (70) in such a way that it moves into its respective opening or regulating position in a pressure-compensated manner due to the force of the energy accumulator (42).

Abstract: A pressure-regulating valve having a valve piston (I0) which is subjected to the action of an energy store and which is guided in longitudinally displaceable fashion in a valve housing (12), which valve housing has ports such as a supply port (14), a utility port (16) and a tank port (18), which ports can be actuated, by way of a control part (20) which closes with a sealing action, such that, in the case of a fluidic connection from the supply port to the utility port, a pressure reduction function is realized, and in the case of a fluidic connection from the utility port to the tank port, a pressure-limiting function is realized, characterized in that the control part (20) has a control rod (22) with two control bodies (24, 26) held spaced apart from one another, of which control bodies one (24) controls at least the fluidic connection between supply port (14) and utility port (16), and the other control body (26) controls at least the fluidic connection between utility port (16) and tank port (18).
