AI Technical Summary

Problems solved by technology

The disadvantage of the described pump is the large chamber that must be filled with compressed air after reaching the dead center, so that the diaphragm can move in the other direction
This requires an extremely large amount of compressed air, which increases the maintenance costs of the pump

Embodiment Construction

[0042] figure 1 A front view of a valve 50 according to the invention with a sound absorber 35 arranged thereon is shown. The valve 50 has a lower housing part 60 and an upper housing part 61 . In the lower housing part 60 is provided a connection 43 to which a pressure line for connection to an external pressure generating device (not shown) can be connected. Valve 50 also has a port D E 、D A ,See Figure 13 and 14 , the pressure generating device 45 can be connected to said interface with its inlet and outlet. As long as compressed air from an external pressure source is connected to the pump inlet 43 , regulated and unregulated air at a certain constant pressure is thus provided within the housing 60 , 61 of the valve 50 .

[0043] figure 2 show cross-based figure 1 A cross-sectional view of the valve 50 on plane A-A. Channels 68 and 69 extending into the plane of the drawing are provided in the lower housing part 60 . In addition, an outlet channel 51 is provide...

Abstract

The invention relates to a valve for alternately filling two working chambers (A, B) of a piston-cylinder system (1, 2, 3) of a pump with a fluid, wherein the valve has two valve pump outlets (PA, PB) for connecting to the working chambers (A, B) of the pump and has a valve control element (64) which is arranged in a displaceable manner, and which can be moved back and forth in a fluid-driven manner, in a chamber of a valve housing (60), wherein the valve control element (64) has control ducts (67, 82, 83, 84) which interact with housing ducts (51, 71, 72, 80, 81) arranged in the valve housing (60), wherein the first valve pump outlet (PB) is connected to the housing ducts (71, 80) and the second valve pump outlet (PA) is connected to the housing ducts (72, 81), wherein in a central region between the two end positions, the valve pump outlets (PA, PB); are connected to one another via control ducts (82, 83, 84) of the valve control element (64).

Description

technical field [0001] The invention relates to a valve for alternately filling two working chambers of a piston-cylinder system of a pump with a fluid, wherein the valve has two valve pump outlets for connection to the working chambers of the pump and a valve control element, the valve The control element is movably arranged in the cavity of the valve housing and can be reciprocated between two end positions in a fluid-driven manner, wherein the valve control element has a control channel, which is arranged in the valve housing. The housing channel in the body cooperates, wherein the first valve pump outlet is connected to the housing channel and the second valve pump outlet is connected to the housing channel. Background technique [0002] Type-dependent valves are required, for example, for filling the working chambers of diaphragm pumps and piston pumps. In diaphragm pumps, the diaphragm delimits a delivery chamber into which an inlet line and an outlet line open. Usua...
