Valve
First Claim
1. A valve, comprising:
- a) a valve housing having a through-flow channel;
b) a valve seal in said through-flow channel;
c) a closure member movable relative to said valve seat;
d) a membrane formed from overlying disks, said membrane having first and second sides attached to said valve housing and said closure member;
e) a seal disposed adjacent said membrane first side and engaged with said closure member for defining in said housing a closed space;
f) a non-compressible deformable support medium fills said closed space; and
g) said closure member is shaped so that the volume of said closed space remains constant during movement of said closure member.

Abstract
A valve (1) has a valve housing (2) traversed by a through-flow channel (3), a valve seat (5) in the through-flow channel (3), and a closure member (13) movable relative to the valve seat (5), wherein the membrane (28) is attached on the outside to the valve housing (2) and on the inside to the closure member (13), whereby a seal (24) is provided on the side of the membrane (28) facing away from the through-flow channel (3) between closure member (13) and valve housing (2), which encloses a support hollow space (29) together with the membrane (28) filled with a non-compressible deformable support medium, wherein the closure member (13) has a shape such that, on the side of the membrane (28) facing away from the through-flow channel (3), the volume of the support hollow space (29) remains essentially constant during movement of the closure member (13).

- 3. Valve (1) with a valve housing (2) traversed by a through-flow channel (3), a valve seat (5) in the through-flow channel (3), and a closure member (13) movable relative to the valve seat (5), wherein a membrane (28) is attached on the outside to the valve housing (2) and on the inside to said closure member (13), characterized in that the side of said membrane (28) facing away from the through-flow channel (3) is provided with a seal (24) between said closure member (13) and said valve housing (2), which, together with said membrane (28), encloses a closed support hollow space (29) filled with a non-compressible deformable support medium, wherein said closure member (13) on the side of said membrane (28) facing away from said through-flow channel (3) is shaped so that the volume of said support hollow space (29) remains essentially constant during movement of said movement of said closure member (13).
