[0004]
These requirements lead to a relatively complex structure of the device, especially the shock absorber, as can be seen for example from US2016 / 0091044A1 and WO2016 / 066314A1
This makes the construction especially complex, since several slide valves have to be used

Embodiment Construction
[0067] figure 1 A circuit diagram of a device 10 for controlling or regulating the pressure of a pressure fluid in a pilot pressure chamber 12 is shown. Hydraulic fluid or compressed air can be used as pressure fluid, wherein the following description refers to pressure fluid designed as hydraulic fluid. The device 10 includes a primary circuit 14 in which pressurized fluid can be conveyed by means of a working machine 16 . A working machine 16 is to be understood as a component with which, in particular, mechanical work can be transferred to the pressurized fluid in such a way that the pressurized fluid is delivered in the delivery direction indicated by the arrow P1 in the primary circuit 14 .
[0068] With respect to the conveying direction indicated by the arrow P1 , downstream of the working machine 16 there is arranged a branch 18 from which a secondary circuit 20 starts, which can also be flowed through by pressurized fluid. The exact design of the secondary loop 20 w...

The invention relates to a pressure regulating valve (30) for controlling or regulating the pressure of a pressure fluid in a pilot pressure chamber (12). The pressure regulating valve (30) comprises a valve housing (50) having at least one inlet (41) and at least one outlet (43); a wall section (51) fixedly connected to the valve housing (50), the wall section (51) having a first through-channel and a first through-hole through which a pressure fluid can flow and which form a first valve seat; a plunger (52) which is mounted in the valve housing (50) so as to be movable along a longitudinal axis (L) by means of an electrically energizable actuating device (49); a first sealing element (54) which is movably supported in the valve housing (50) along the longitudinal axis (L) and is biased by means of a first spring (56) into a closed position in which the first sealing element (54) bears against the first valve seat (58) and closes the first through-hole, wherein the first sealing element (54) has a second through-channel (60) through which a pressure fluid can flow, wherein the second through-channel (60) can be fluidically connected to the first through-channel; a second sealing element (64) which is fastened at the plunger (52) and can be moved along the longitudinal axis (L) by means of the plunger (52) by energization of the actuating device (49) between a first position at which the second sealing element (64) rests against the wall section and closes the first through-passage and a second position at which the second sealing element (64) closes the second through-passage along the longitudinal axis (L). The second sealing element (64) abuts the second valve seat (66).
Description
technical field [0001] The invention relates to a pressure regulating valve for controlling or regulating the pressure of a pressure fluid in a pilot pressure chamber. The invention also relates to a device having such a pressure regulating valve, with which the pressure of the pressure fluid in the pilot pressure chamber can be adjusted. Background technique [0002] Hydraulic fluid or compressed air is usually used as pressure fluid. A pilot pressure chamber in a hydraulic or pneumatic operating device is used to control or regulate a pilot valve, which is usually also implemented as a hydraulic or pneumatic slide valve. When the pilot valve is designed as a proportional valve or a proportional spool valve, the volume flow through the proportional valve or proportional spool valve can be set steplessly within a certain range with the pressure in the pilot pressure chamber. [0003] An example of such a hydraulically or pneumatically operated device is a shock absorber in...
