A valve for limiting the tank pressure in a motor vehicle, comprising a first line (1) and a second line (2) which may establish a flow connection in which at least one body (3, 4) may be moved relative to another body (4, 3), whereby the movable body (3, 4) lifts up from a sealing seat (5), with re
A valve for limiting the tank pressure in a motor vehicle, comprising a first line (1) and a second line (2) which may establish a flow connection in which at least one body (3, 4) may be moved relative to another body (4, 3), whereby the movable body (3, 4) lifts up from a sealing seat (5), with regard to the object of adjusting the tank pressure using a compact design is characterized in that a first body (3), a second body (4), and the sealing seat (5) as a whole form a movable unit (6).

1. A valve for limiting the tank pressure in a motor vehicle, comprising a first line and a second line in a housing having two sections, wherein the first line is separated from the second line in a fluid-tight manner by means of a roller diaphragm and a single sealing seat; anda flow connection fo
1. A valve for limiting the tank pressure in a motor vehicle, comprising a first line and a second line in a housing having two sections, wherein the first line is separated from the second line in a fluid-tight manner by means of a roller diaphragm and a single sealing seat; anda flow connection for fluid capable of being established between said first line and said second line whereina first body is movable relative to a second body whilst said second body is fixed in place and said second body is movable relative to said first body whilst said first body is fixed in place, wherein said first body is braced against said second body via a spring and said sealing seat includes an elastomeric seal associated with said first body and a circumferential collar having a tapered design associated with said second body, wherein said first body has passages defined through said first body which establish a fluid-conducting connection between said first line and a sealing seat chamber enclosed by the first body and the second body, wherein one of said first body and said second body lifts up from said sealing seat when movable relative to the other body, and wherein said first body, said second body, and said sealing seat as a whole form a movable unit and wherein said fluid can flow out of the sealing seat chamber from the first line to the second line when said first body moves relative to said second body and fluid can flow through the sealing seat chamber from the second line to the first line when said second body moves relative to said first body and wherein the roller diaphragm is clamped to said second body and between said two housing sections and is able to rest against a rounded support shoulder that projects from the housing wall; anda guide connected to said first moveable body, wherein said guide provides a support shoulder for said spring bracing said first body to said second body and said guide interacts with said housing to guide said movable unit in said housing without jamming or tilting. 2. The valve according to claim 1, characterized in that a first stop is associated with the unit, and is able to rest against the first body, with the second body being movable relative to the first body. 3. The valve according to claim 1, characterized in that a second stop is associated with the unit and is able to rest against the second body, with the first body being movable relative to the second body. 4. The valve according to claim 1, characterized in that the first body and the second body are pressed against one another via the spring in a fluid-tight manner at the sealing seat. 5. The valve according to claim 1, characterized in that the first body forms a first pressure engagement surface having a diameter, and the second body forms a second pressure engagement surface having a diameter. 6. The valve according to claim 5, characterized in that when the first body contacts a first stop, an effective pressure engagement surface results which corresponds to the difference in diameter in the two pressure engagement surfaces. 7. The valve according to claim 5, characterized in that when the second body contacts a second stop, an effective pressure engagement surface results which corresponds to the first pressure engagement surface.
