Patent attributes
An electromagnetic shuttle valve with two valve passages (5, 6) provides an increased cross-section of the second valve passage (6) by increasing the diameter of the second valve closure member (8). To this end, a compression spring (17) which biases the second valve closure member towards the first valve closure member (7) is arranged inside the second valve closure member (8) and the second valve seat (27). It abuts a radial projection formed on the housing sleeve (1) below the second valve seat (27). In order to provide an even larger cross-section of the second valve passage (6), the housing sleeve diameter can increase around the second valve seat (27). In this case, the housing sleeve can include a bulged collar 9 to provide a stop for axial movement during assembly.
