A residual pressure valve (10; 10a; 10b) for a flow medium, in particular for air, the flow passage (30) of which is arranged in a valve housing (15) and is designed so as to allow flows to pass in different directions and so as to be interrupted by an at least partially movable sealing element (41; 41a) depending on the pressure of the flow medium, wherein an energy store (45) which is in particular designed as a pressure spring, the sealing element (41; 41a) is seated against a counter element (21; 21a) in a sealing manner when the flow medium drops below a minimum pressure in order to interrupt the flow passage (30), and wherein the flow path (30) has two separate bores (32, 58) which are arranged coaxially in relation to one another and are connected to one another by at least one connecting channel (33). |

1. A residual pressure valve (10; 10a; 10b) for a flow medium, comprising: a flow passage (30) which is arranged in a valve housing (15) and is adapted to allow flow in a first or a second direction wherein the second direction is opposite to the first direction, wherein flow is interrupted by means of an at least partially movable sealing element (41; 41a) activated depending on a pressure of a flow medium, wherein an energy store means (45) is designed as a pressure spring and the sealing element (41; 41a) is seated against a counter element (21; 21a) in a sealing manner when the flow medium drops below a minimum pressure in order to interrupt the flow passage (30), wherein the flow passage (30) has two separate bores (32, 58) which are arranged coaxially in relation to one another and are connected to one another by at least one connecting channel (33), wherein the at least one connecting channel (33) is constructed in a first part (17; 17b) of the valve housing (15), which has a mount (40) for the at least indirect sliding guidance of the sealing element (41; 41a) and is adapted to receive the energy store means (45), and wherein the connection between a first bore of the two separate bores (58) and the at least one connecting channel (33) takes place via an annular space (28) which is arranged symmetrically to a longitudinal axis (20) of the valve housing (15) between the first part of the valve housing (17; 17b) and a second valve housing part (16; 16a; 16b) radially surrounding the valve housing first part (17; 17b) in a region of the flow path (30), wherein the sealing element (41; 41a) is arranged directly in the mount (40), and the energy store means (45) is arranged in a space formed by the mount (40) and the sealing element (41; 41a), which space is connected with the environment by means of at least one vent bore (49), wherein the counter element (21; 21a) is formed by a wall section (21a) of the second valve housing part (16) circumferential radially to the longitudinal axis (20) of the valve housing (15). |
