Patent ID: 8627838

Claim:
A rotary impingement cleaning apparatus for sanitary environments, comprising: a. a housing having a first axis; b. an inlet cap mounted to the housing for introducing a pressurized cleaning liquid therethrough; c. a stator affixed within the housing concentric with the first axis at an upstream end thereof, the stator being configured for changing the flow path of the cleaning liquid; d. a rotator stem rotatably mounted within the housing to be concentric with the first axis and downstream of the stator, the rotator stem being rotationally driven by the cleaning liquid; e. an elbow having a first portion aligned with the first axis and a second portion having a second axis, the elbow mounted to the rotator stem for rotation therewith as driven by the cleaning liquid; f. a nozzle housing rotatably connected to the second portion of the elbow for rotation around the second axis; g. nozzle means for discharging the cleaning liquid outward from the nozzle housing; h. gear means for causing the nozzle housing to rotate around the second axis as the elbow rotates around the first axis; i. whereas the pressurized cleaning liquid enters the housing, passes through the stator, drives the rotator stem to rotate, passes through the elbow into the nozzle housing, and is discharged through the nozzle means to impinge inner surfaces of a tank being cleaned; and j. whereas mating components of the cleaning apparatus fit together loosely to enhance self flushing and liquid drainage.
