Abstract
A fluid pump includes a housing having a lateral wall and an end wall, an insert located in the housing surrounded by the lateral wall and including a body having a central aperture and inlet and outlet fluid channels. A seal, located between the end wall and the insert, seals against fluid flow therebetween. A Gerotor pump mechanism located in the housing adjacent the inlet and outlet fluid channels includes a outer gear and an inner gear engaged with the outer gear for pumping fluid from the inlet fluid channel to the outlet fluid channel as the inner gear rotates relative to the outer gear. A cover, fitted in the housing and spaced axially from the end wall, is located adjacent the inner gear and outer gear and is secured to the housing.
