Beschreibung
Zusammenfassung:	A shuttle valve (2) is disclosed. The shuttle valve (2) comprises a valve body (18, 20), a valve member (6), and a catch (8). The valve body (18, 20) comprises a first and a second fluid inlet (10, 12), a central chamber (14), and a fluid outlet (16). The first and second fluid inlets (10, 12) and the fluid outlet (16) open into the central chamber (14) via a first and a second inlet mouth (28, 44) and an outlet mouth. The valve member (6) is configured to move between a first and a second position, the valve member (6) closes the first inlet mouth (28) and allows fluid communication between the second inlet mouth (44) and the outlet mouth when the valve member (6) is in the first position, and the valve member (6) closes the second inlet mouth (44) and allows fluid communication between the first inlet mouth (28) and the outlet mouth when the valve member (6) is in the second position. The catch (8) exerts a biasing force against the valve member (6) and the valve member (6) and catch (8) are so configured that the catch biasing force biases the valve member (6) to close the first inlet mouth (28) when the valve member (6) is in the first position and to close the second inlet mouth (44) when the valve member (6) is in the second position.
