Embodiment Construction

[0025] figure 1 is a schematic view of the fluid valve 10a of the first embodiment in two positions. The fluid valve consists of two valve chambers 52 a , 52 b separated from each other by means of a seal 50 . The two valve chambers 52a, 52b each have an inlet 54a, 54b and an outlet 56a, 56b. The two inlets 54a, 54b preferably communicate with each other in a manner not shown. There is an S-shaped elastic strap element 58 extending inside the two valve chambers 52a, 52b, which strap element 58 is pivotally mounted at the center of the sealing part 50 and is pivotally supported at both ends 53 at Two adjusting screws 60a, 60b. Thus, the sealing portion 50 forms a pivot point 51 for a strap element 58 .

[0026] The strip element 58 has the function of a flap which is positionally variable and presses with a defined pre-pressure onto the valve seat of the outlet 56a, 56b, thereby closing the outlet 56a, 56b. Fluid pressure presses the strap element 58 to the valve seat, t...

Abstract

The invention relates to a bistable fluid valve (10) which is characterized by two valve chambers (52a, 52b) which are arranged next to each other and are separated against each other by a partition (50), said valve chambers comprising an inlet (54a, 54b) and an outlet opening (56a, 56b) which are in each case located opposite each other, an S-shaped elastic strip element (58) that penetrates both valve chambers (52a, 52b) and is supported in an articulated manner in the region of the partition (50) and can have two positions in which it sealingly closes either the one or the other outlet opening (56a, 56b). Furthermore, the fluid valve is characterized by an actuating element (62) which is fixed to the strip element (58) and by which the strip element (58) can be switched between both positions. The fluid valve (10) according to the invention only comprises a single movable component having a small mass that can thus be operated with quick reactions.

Description

technical field [0001] The present invention relates to a bistable fluid valve. Background technique [0002] In most hydraulic systems, directional valves or shut-off valves are used to reverse or shut off the volume flow of fluid. Dedicated actuation components, power supply and control electronics are required to control the valve. If fast switching valves with high actuation frequencies are required, there are unavoidable high electrical losses caused by the control valves. Contents of the invention [0003] Starting from this, the invention is based on the object of providing a bistable fluid valve which has a structurally simple design and is able to work in a fast-reacting manner due to the low moving mass. [0004] The invention is derived from the characteristics of the independent proposals. The subdivisions relate to advantageous refinements and implementations. Further features, possible uses and advantages will emerge from the following description and the...
