Abstract
A vertically oriented high pressure water pump system including a vertically oriented motor, an intermediate flange and an axial drive water pump wherein the intermediate flange verticaly unites the motor and the high pressure water pump and further includes an axial thrust bearing and a thrust bearing sleeve for coupling the motor drive shaft in the axial drive pump.
Claims17
A vertically oriented high pressure water pump system comprising:
- an motor including a motor housing and a downwardly oriented vertical drive shaft;
- an axial drive pump driven by the drive shaft;
- an intermediate flange between the axial drive pump and the motor and including a first recess;
- an axial thrust bearing located in the first recess of the intermediate flange;
- and
- a drive shaft sleeve attached to the drive shaft and at least partially surrounded by the axial thrust bearing such that rotation of the drive shaft causes the thrust bearing and the drive shaft sleeve to rotate in unison.

A vertically oriented high pressure water pump system comprising:
- a motor including a motor housing and a downwardly oriented vertical drive shaft;
- a pump driven by the drive shaft;
- an intermediate flange interposed between said motor housing and said pump, said intermediate flange including a first recess;
- an axial thrust bearing located in the first recess of the intermediate flange;
- and
- a drive shaft sleeve attached to the drive shaft and at least partially surrounded by said axial thrust bearing such that rotation of the drive shaft causes the thrust bearing and the drive shaft sleeve to rotate in unison.

A vertically oriented high pressure water pump system comprising:
- an internal combustion engine including a motor housing and a downwardly oriented vertical drive shaft having an end;
- an intermediate flange having an aperture, first and second annular recesses, and a plurality of first bolt apertures;
- an axial thrust bearing located in the first recess of the intermediate flange;
- a drive shaft sleeve attached to the drive shaft and at least partially surrounded by the axial thrust bearing such that the rotation of the drive shaft causes the thrust bearing and the drive shaft sleeve to rotate in unison;
- an axial drive piston pump including a plurality of second bolt apertures complementary to the first bolt apertures;
- a bolt associated with each first and second bolt aperture for compressively securing the intermediate flange between the motor and the axial drive piston pump;
- and
- a wobble disc assembly for driving the axial drive piston pump located in the second recess for the intermediate flange and attached to the end of the drive shaft.

A vertically oriented high pressure water pump system comprising:
- an internal combustion engine including a motor housing and a downwardly oriented vertical drive shaft having an end;
- an intermediate flange having an aperture, a first recess, a second recess and a plurality of first bolt apertures spaced at 120.degree. intervals around the circumference of the intermediate flange;
- an axial thrust bearing fixedly located in the first recess of the intermediate flange;
- a drive shaft sleeve attached to the drive shaft and at least partially surrounded by the axial thrust bearing such that the rotation of the drive shaft causes the thrust bearing and the drive shaft sleeve to rotate in unison;
- an axial drive piston pump including a plurality of second bolt apertures complementary to the first bolt apertures;
- a bolt associated with each first and second bolt aperture for compressively securing the intermediate flange between the motor and the axial drive piston pump;
- a wobble disc assembly located in the second recess of the intermediate flange and attached to the drive shaft end for driving the axial drive piston pump;
- and
- a horizontal platform and a plurality of vibration dampeners each having a first threaded end associated with the horizontal platform and a second threaded end associated with the intermediate flange, the vibration dampeners securing the high pressure pump assembly to the horizontal platform.
