| 摘要 |
The invention relates to a valve mechanism (1; 1′) for controlling a fluid, comprising a housing (2; 2′) that has a fluid duct (3), further comprising a valve body (5) that is mounted on the housing (2) so as to be adjustable between an open position in which the valve body allows the fluid (F) to flow through the fluid duct (3) and a closed position in which the valve body fluid-tightly seals the fluid duct, and comprising a membrane-like sealing element (13) which is secured to the housing (2) at a first end portion (14) and to the valve body (5) at a second end portion. In the open state of the valve body (5), a side of the sealing element (13) that faces away from the fluid duct (3) rests against a wall section (17) between the two end portions (14, 15). |

1. A valve mechanism (1; 1′) for controlling a fluid, in particular an abrasive high-viscosity material, comprising:
a housing (2; 2′) having a fluid duct (3; 3′), a valve body (5; 5′) mounted on the housing (2; 2′) so as to be adjustable between an open state, in which said valve body opens up the fluid duct (3; 3′) for fluid flow with the fluid (F; F′), and a closed state, in which said valve body closes the fluid duct (3; 3′) in a fluid-tight manner, and with a sealing element (13; 13′) defining a diaphragm that is fastened by a first end portion (14; 14′) to the housing (2; 2′) and by a second end portion to the valve body (5; 5′), wherein the sealing element (13; 13′), at least in the open state of the valve body (5; 5′), is supported by a side facing away from the fluid duct (3; 3′) against a wall portion (17; 17′) in a region between the two end portions (14, 15; 14′, 15′). |
