1. An arrangement (2) for manipulating the flow of a fluid into and out of a fluid actuator (4), preferably of a seat, wherein the arrangement (2) comprises a base body (5) having an opening (13) designed to introduce the fluid into the base body (5), and at least one further opening (10-12) provided for forwarding or discharging the fluid introduced into the base body (5), wherein means are provided for establishing and/or interrupting a fluid-conducting connection between the openings (10-13),
wherein the means for establishing and/or interrupting a fluid-conducting connection between the openings (10-13) comprise such additional means (14, 15) that can be charged with a pressure of the fluid to be conducted and are designed such that, in a first pressure range (R1) of the fluid, the fluid entering the base body (5) from the fluid actuator (4) is discharged via one of the openings (10) from the base body (5) to the surroundings and, in a second pressure range (R2) of the fluid that is higher than the first pressure range (R1), the fluid introduced into the base body (5) is introduced into the fluid actuator (4),
wherein the additional means comprise a first valve (14) that is open in its normal position (OP1), and a second valve (15) that is closed in its normal position (CP2), wherein the valves (14, 15) can be charged with a pressure of the fluid to be conducted and are designed such that, in a first pressure range (R1) of the fluid, the first valve (14) remains in its open normal position (OP1) and the second valve (15) is transitioned from its closed normal position (CP2) into an open switching position (OP2), whereas, in a second pressure range (R2) of the fluid that is higher than the first pressure range (R1), the second valve (15) remains in the open switching position (OP2) or is transitioned into said open switching position, and the first valve (14) is transitioned from its open normal position (OP1) into a switching position (CP1) that is closed in relation to said open normal position.
