ABSTRACT:
Separate valve bodies (16, 18) are connected by a sleeve (24). The joint (26) between the first body (16) and the sleeve (24) is detachable by bending forces and resistant to tension forces. The joint (32) between the second body (18) and the sleeve (24) is detachable by tension forces and resistant to bending forces. Each joint (26, 32) includes an annular groove (28, 34) on the valve body (16, 18) and portions (30, 36) of the sleeve (24) extending radially into the groove (28, 34). Each valve body (16, 18) has a valve element (44) that moves axially inwardly to close the flow passage (42) when one of the joints (26, 31) is detached. The valve element (44) is normally retained in an open position by a ball detent (84). A projection (82) carried by the confronting valve body (16, 18) holds the ball (84) in a groove (62) on the element's shaft portion (56). In a vehicle (2) having two fuel tanks (4) connected by a crossover line (10), a valve (14) is positioned at each end of the line (10) between the line (10) and the associated tank (4).
