Abstract

A viscous shear fluid clutch comprising a shaft element have an input drive connection at one end; a rotary casing (28) mounted for rotation relative to said shaft element; an inner clutch member fixed rotationally with respect to said shaft element and disposed within said casing and spaced therefrom by a clearance gap; a fluid reservoir (40) communicating with said clearance gap; pump means (42) arranged to pump fluid in use from the clearance gap to the reservoir in response to relative rotation between the casing and the inner clutch member; and valve means arranged to control the flow of fluid between the pump means and the clearance gap and including a variable control member; said rotary casing is mounted for rotation on said shaft element by means of a bearing arrangement (36) acting between the shaft element (12) and said casing (28) and disposed to the side of the clutch member remote from said input drive.
