Housing assembly for a fluid-working device such as a rotary pump

摘要

Outer ends of inlet and outlet ducts have annular grooves, in lieu of bolt-holed flanges, to receive the inwardly-extending rims of a two-piece, clamping coupler. The coupler joins a conduit, which has a bight, to the inlet duct, in order to change an end-suction configuration of the device to an in-line configuration, selectively.
