Abstract: A fluid-dispensing nozzle including a nozzle body. A discharge tube is disposed in the nozzle body and has a plurality of cam grooves. The nozzle further includes a rotatable flow control. A pin is coupled to the flow control and rotatably engages a select cam groove such that rotation of the flow control causes the pin to rotatably slide in the select cam groove, causing the discharge tube to move linearly. A first and a second insert are coupled to the nozzle body, the first insert having a cam slot. The nozzle also includes a rotatable pattern sleeve. A cam follower is coupled to the pattern sleeve and engages the cam slot of the first insert. A determinable pattern of motion of the pattern sleeve is controlled by the first and second inserts. The first and second inserts are rearrangeable to change the pattern of motion of the pattern sleeve.

Abstract: A pump control system includes a source of pressurized fluid an output valve adjustably controls the flow of pressurized fluid from the source. An output valve control is coupled to the output valve and monitors the actual state of the output valve. The control selectably adjusts the output valve in response to a first control signal. A controller is coupled to the output valve control, the controller receiving information from the output valve control corresponding to the actual state of the output valve and providing to the output valve control the first control signal, the first control signal being applied to the output valve to achieve and maintain a desired state.
