ABSTRACT OF THE DISCLOSURE A variable displacement pump has a displacement control cam operably connected to a displacement control cylinder within a pump housing and a pressure and flow sensitive compensating valve is connected to the pump housing for regulating output of the pump. The compensating valve is secured to the pump housing through a spacer block. A lever is disposed partly in the spacer block and partly in a housing of the compensating valve responsive to positioning of the pump cam through a mechanical connection for actuating a sleeve in the compensating valve to incorporate torque-limiting feedback regulation of the pump. An adjustment is operable from an outer surface of the spacer block to limit torsional operation of the lever about a pivot point.
