摘要： A flow limiting and temperature compensated orifice assembly includes a valve body having an orifice and a plurality of exterior bypass channels or openings. The valve body is disposed in a complementary cylindrical chamber in a housing in the fluid line which also receives a bi-metallic disc and a rubber washer. The bi-metallic disc is disposed adjacent one end of the body and defines a center opening which aligns with the orifice opening. In a first, higher temperature position or state, the bi-metallic disc engages the adjacent end face of the body and closes off flow through the exterior channels and allows fluid flow only through the flow limiting and thus torque controlling orifice. In a second, lower temperature position or state, the bi-metallic disc has flipped and moved away from the end face of the body and allows fluid flow through the exterior bypass channels as well as the orifice opening.
