A sliding vane positive displacement pump with a spring biased mechanical vane acutating system. The pump includes a case having an inlet and an outlet with a liner having a cam-shaped inner surface eccentrically disposed therein. A rotor having radially oriented slots is rotatably positioned within the case, and radial holes interconnect opposite pairs of slots. A vane is slidingly positioned in each slot. A vane actuator assembly, including a hollow sleeve with a plinger reciprocably disposed therein, is installed in each slot. A spring is positioned in the sleeve and bears against one end of the plunger and a closed end of the sleeve. The spring biases the sleeve and plunger so that each is in contact with the inwardmost edge of a vane. Each plunger defines a slot therein, and each sleeve defines a transverse hole therethrough corresponding to the slot. A pin, pressed into the transverse hole, extends through the slot for preventing the plunger and sleeve from becoming separated. The sleeve also defines pressure relieving holes so that as the plunger moves toward the sleeve, pressure in the sleeve is relieved.
