  • Valves, and seismic sources incorporating the valves
    Patent number: 6869061
    Abstract: A valve has an input (3,13) and first and second outputs (4, 5; 14, 15). The valve also has a closure member (2, 12) that is operable to isolate the first output from the input, to isolate the second output from the input, to isolate both outputs from the input, or to connect both outputs to the input. In one embodiment, the input (13) and the first and second outputs (14, 15) are disposed in a flat valve face (16) in a valve body. The closure member (12) has a sealing face (17?) that is biased against the valve face (16). A recess (18) is provided in the sealing end face (17?) of the closure member (12). The recess is so shaped, and the input (13) and outputs (14, 15) are so positioned that rotation of the closure member (12) by successive angles of 90° puts the valve in the following states: both outputs connected to the input, one of the outputs connected to the input, the other of the outputs connected to the input, and both outputs isolated from the input.
