Mixer nozzle assembly
First Claim
1. A mixer nozzle assembly for mixing fluid introduced into a tank having a tank volume therein, the mixer nozzle assembly comprising:
- a stationary body comprising at least one inlet and at least one outlet in fluid communication with each other;
a rotatable body mounted on the stationary body for rotation about an axis in a predetermined direction, the rotatable body comprising at least one intake aperture and at least one outlet aperture in fluid communication with each other, said at least one intake aperture being in fluid communication with said at least one outlet of the stationary body for permitting the fluid to flow from said at least one inlet of the stationary body to said at least one outlet aperture, to exit therefrom into the tank volume;
said at least one outlet aperture being formed to direct the fluid exiting the rotatable body therethrough in a direction non-aligned with the axis, for causing the rotatable body to rotate in the predetermined direction about the axis;
the fluid exiting said at least one outlet aperture mixing with at least a part of the fluid in the tank volume;
a governor subassembly for controlling a speed of rotation of the rotatable body in the predetermined direction about the axis, the governor subassembly comprising;
a driveshaft secured to the rotatable body for rotation with the rotatable body about the axis at the speed of rotation;
at least one internal element attached to the driveshaft, for rotation with the driveshaft about the axis at the speed of rotation;
a governor body defining at least one cavity therein in which said at least one internal element is receivable to at least partially define an internal volume between said at least one internal element and the governor body;
the internal volume being adapted to receive hydraulic fluid directable therethrough at a preselected flow rate to moderate rotation of said at least one internal element about the axis, for causing the rotatable body to rotate at a preselected speed;
a hydraulic circuit for governing a flow rate of the hydraulic fluid to adjust the flow rate to the preselected flow rate, for adjusting the speed of rotation of the rotatable body to the preselected speed;
a speed indicator for indicating the speed of rotation of the rotatable body about the axis relative to the stationary body, the speed indicator comprising;
at least one first element stationary relative to the rotatable body, said at least one first element comprising a first engagement portion;
at least one second element mounted on the rotatable body, said at least one second element comprising a second engagement portion; and
each said second engagement portion being positioned for engagement with the first engagement portion at time intervals as the rotatable body rotates about the axis relative to the stationary body, for providing an audible signal to indicate the speed of rotation of the rotatable body relative to the stationary body.

Abstract
A mixer nozzle assembly for mixing fluid introduced into a tank having a tank volume therein. The mixer nozzle assembly includes a stationary body and a rotatable body mounted on the stationary body for rotation about an axis in a predetermined direction. The fluid flows through the stationary body to the rotatable body and exits into the tank volume via one or more outlet apertures for causing the rotatable body to rotate in the predetermined direction about the axis. The mixer nozzle assembly also includes a governor subassembly for controlling a speed of rotation of the rotatable body in the predetermined direction about the axis and a hydraulic circuit for governing a flow rate of hydraulic fluid directed to the governor subassembly, to adjust the flow rate of the hydraulic fluid for adjusting the speed of rotation of the rotatable body to the preselected speed.
