Abstract
The present invention is directed to a simplified viscosity compensating circuit which utilizes a viscosity sensitive capillary and a flow restriction means in series therewith to regulate the pressure at a particular point in a control circuit in response to a change in viscosity of the control fluid. Such viscosity compensation in the circuit is utilized to either maintain a uniform pressure at the circuit output or off-set an adverse condition caused by a change in viscosity of the control fluid.
