Abstract
Abstract There is provided a drive for an orbital nozzle comprising a housing having a fluid inlet and containing a fluid driveable impeller from which the fluid, in use of the drive, flows through a passage within the housing, an epicyclic rotary speed reducing mechanism in the housing, an output shaft driven by the epicyclic at speed reduced below the impeller speed, an element driveable by the output shaft mounting the nozzle for rotation, including an element for delivering fluid from the passage to the nozzle, as well as an orbital nozzle unit which incorporates such a drive and a hydraulic cleaning head which incorporates such a drive or orbital nozzle unit.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
142 words
A drive for an orbital nozzle, comprising a housing having a fluid inlet, a fluid driven impeller disposed proximate to said inlet, a fluid passage within the housing extending from said inlet to an outlet, an epicyclic rotary speed reducing gear unit within said housing, said gear unit having an input formed by said impeller, an output shaft driven by the gear unit at a speed reduced below the speed of said impeller, means driveable by said output shaft and mounting the nozzle for rotation, including means for delivering fluid from said outlet of said passage to said nozzle, and wherein said gear unit is made of stainless steel and is provided with non-corrosive plastic bearing bushes, and wherein said passage surrounds said gear unit such that fluid flowing through said passage acts to dissipate frictional heat generated in the gear unit.
Claim 2
Dependent Claim
142 words
A drive for an orbital nozzle, comprising a housing having a fluid inlet, a fluid driven impeller disposed proximate to said inlet, a fluid passage within the housing extending from said inlet to an outlet, an epicyclic rotary speed reducing gear unit within said housing, said gear unit having an input formed by said impeller, an output shaft driven by the gear unit at a speed reduced below the speed of said impeller, means driveable by said output shaft and mounting the nozzle for rotation, including means for delivering fluid from said outlet of said passage to said nozzle, and wherein said gear unit is made of stainless steel and is provided with non-corrosive plastic bearing bushes, and wherein said passage surrounds said gear unit such that fluid flowing through said passage acts to dissipate frictional heat generated in the gear unit.
Claim 3
Dependent Claim
62 words
A drive according to claim 1, wherein the epicyclic gear unit comprises a sun gear, a double planet gear, a stationary ring gear and an output ring gear, with one gear of the double planet gear meshing with the stationary ring gear and the other meshing with the output ring gear, two pairs of idling planet gears being fitted at equal spacing.
