ABSTRACT:
A fluid connection and control device for fluid machines permits fluid inlet or outlet connections without the necessity for threaded connection to the machine. This is accomplished by an elongate radially symmetrical body having first and second ends and a central axial fluid passage connecting the ends. The body is appropriately sized for the fluid channel of the fluid machine and has a provision at the first end for attachment of a flexible hose. The second end has a provision for a fluid tight seal between the body and the fluid channel as well as a mechanism by which the body is retained within the fluid channel of the fluid machine while permitting rotation thereof. Options are provided for incorporation of a valve mechanism for controlling the fluid flow. This provides the advantages of rapid assembly and avoidance of undue stresses to the fluid machine housing.
