Abstract
An adjustable mechanical coolant pump for an internal combustion engine includes a pump rotor wheel comprising an axial inlet. The pump rotor wheel is configured to pump a coolant radially outwardly. Variable pump stator blades are arranged so as to pivot radially outwardly at a circle concentrically with the pump rotor wheel. A control ring is configured to pivot the variable pump stator blades when the control ring is rotated. An actuator is configured to rotate the control ring so as to pivot the variable pump stator blades between an open position and a closed position. A pump housing body is configured to support the variable pump stator blades and the control ring. A separate static blade holding frame is mounted to the pump housing body. The variable pump stator blades and the control ring are captively mounted at the separate static blade holding frame.
