Abstract
A mechanism, such as a motor driving a pump, creates a pulsating fluid flow. A sensor senses an operating condition of the system and provides a signal representative of the condition. A controller responsive to the signal controls the pulsating fluid flow mechanism in a predetermined manner in accordance with the condition sensed. In one aspect the sensor is a pressure transducer which senses when a throttle valve on a lavage head shuts off or turns on the fluid flow and provides a signal to a controller which shuts off or turns on the motor. In another aspect the sensor is a thermistor which senses the temperature of the motor and provides a signal for controlling the power input to the motor to compensate for the effect of temperature on the performance of the motor.
