Abstract
A combination in-line type water pump and power steering pump assembly which includes a power steering shaft with an outer end portion extending into a pumping chamber of the water pump. The outer end portion of the shaft is configured to removably support a tubular shaft sleeve and a water pump impeller thereon. A seal annulus is mounted in the pump housing and encompasses the shaft sleeve in water tight relation therewith at an inwardly location from the impeller. The impeller and the seal annulus are removable from the sleeve by application of an axial force to slip the impeller and seal annulus axially along the outer end of the shaft sleeve.
Claims14
A water pump comprising:
- a pump housing having a pumping chamber;
- a rotatable shaft having an impeller-driving portion extending into said pumping chamber;
- a shaft and bearing carrier for supporting said shaft for rotation;
- a tubular shaft sleeve axially fitted over the impeller-driving portion of said shaft;
- an impeller removably secured on the outermost diameter of said shaft sleeve adjacent an outer end thereof;
- a seal annulus mounted in said housing and encompassing the shaft sleeve in water tight relation therewith at a point more remote from the outer end of said shaft sleeve than said impeller;
- said seal annulus being removable by being axially slipped over the outer end of said shaft sleeve when said impeller is removed.
An in-line water pump and power steering pump assembly, comprising:
- a power steering pump having a rotatable shaft;
- a water pump having a pump housing defining a pumping chamber;
- said rotatable shaft having an impeller-driving portion extending into the pumping chamber;
- a tubular shaft sleeve axially fitted over the impeller-driving portion of said shaft;
- an impeller removably secured on the outermost diameter of said shaft sleeve adjacent an outer end thereof;
- a seal annulus mounted in said housing and encompassing the shaft sleeve in water tight relation therewith at a point more remote from the outer end of said shaft sleeve than said impeller;
- said seal annulus being removable by being axially slipped over the outer end of said shaft sleeve when said impeller is removed.
