Abstract
A coupling apparatus (10) for connecting a reversible pump (14) having first and second ports (24,26) to a fluid source (16) and to a user device (20) includes a first manifold (30) connected to the pump (14) and a second manifold (32) connected to the first manifold (32). The second manifold (32) has first and second inlet passages (52,56) and one of them is connected to the fluid source (16) and the other is blocked by a plug member (78). The first manifold (30) can be disposed in one of two positions of fluid communication with the pump ports (24,26) by disassembly and assembly of the apparatus (10) to accommodate for reverse operation of the pump without a piece part change and while maintaining system reliability. The coupling apparatus (10) is particularly useful in a marine transmission.
