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.
Claims8
A vertically oriented high pressure water pump system comprising:
- an internal combustion engine including an motor housing, a downwardly oriented vertical drive shaft having an end, and a plurality of motor bolt apertures;
- an intermediate flange having an aperture, a first recess, a second recess, and a plurality of first bolt apertures;
- an axial thrust bearing located in the first recess of the intermediate flange;
- a drive shaft sleeve located in the intermediate flange aperture and 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;
- an axial drive piston pump including a plurality of pump bolt apertures, each pump bolt aperture complementary to a first bolt aperture and complementary to a motor bolt aperture;
- a bolt associated with each first bolt aperture, pump bolt aperture;
- and motor bolt aperture for compressively securing the intermediate flange between the motor and the axial drive piston pump;
- and
- a wobble disc assembly attached to the end of the drive shaft and located in the second recess of 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 an motor housing, a downwardly oriented vertical drive shaft having an end, and a plurality of motor bolt apertures;
- an intermediate flange having an aperture, a first recess, a second recess, a plurality of first bolt apertures and a plurality of second bolt apertures spaced at 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 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 pump bolt apertures, each pump bolt aperture being complementary to a first bolt aperture and to a motor bolt aperture;
- a bolt associated with each first bolt aperture, pump bolt aperture;
- and motor 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 wheeled horizontal platform and a plurality of vibration dampeners each having a first threaded end associated with the wheeled horizontal platform and a second threaded end associated with a first bolt aperture, the vibration dampeners securing the high pressure water pump assembly to the wheeled horizontal platform.
