    摘要: Automatic starting fluid injection systems are useful, for example, to aid in the cold-starting of diesel engines. In the subject invention, a microprocessor under software control is used to controllably inject starting fluid into an engine passageway, such as an intake manifold. During engine cranking, the microprocessor delivers an injection signal to a fluid delivery system to effect starting fluid injection into the engine passageway. When the engine starts, a subsequent injection time is calculated based on the sensed engine temperature. The microprocessor continues to deliver the injection signal to the fluid delivery system during the subsequent injection time.

    摘要: 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.

    摘要: A mechanism, such as a motor driving a pump, creates a pulsating fluid flow. There is a control for varying the pulsation frequency independently of the fluid pressure or rate of flow. Another control varies the pressure or rate of fluid flow independently of the frequency of pulsation. Separate pulsatile lavage, irrigation, and aspiration functions are provided. In another aspect, the mechanism for producing the pulsating flow includes a fluid driving means, such as a reciprocating pump, and there is a means for varying the length of stroke of the driving means.

    摘要: A fluid pump 20 used in a lavage instrument 10 that is driven by vacuum pressure is disclosed. Fluid pump 20 includes a fluid housing 30 connected to an external fluid source and a pneumatic cylinder 50 connected to an external vacuum source. A diaphragm 40 is shiftably disposed within fluid housing 30 to define an inner fluid chamber 31. Pneumatic cylinder 50 includes a cylinder casing 60 and a reciprocating piston 70, which defines a vacuum chamber 61. Piston 70 includes a poppet valve 80 and is connected to diaphragm 40 by two push rods 68. Negative pressure within vacuum chamber 61 draws piston 70 forward and compresses a return spring 67. As piston 70 is drawn forward, piston 70 pushes diaphragm 40 forward to expel fluid from fluid chamber 31 through an outlet port 36. Piston 70 is drawn forward until poppet valve 80 is unseated by its engagement with a post 66 which extends longitudinally from casing end wall 44. Unseating poppet valve 80 equalizes the pressure within vacuum chamber 61 and allows return spring 67 to push piston 70 and diaphragm 40 rearward. Fluid is drawn into fluid chamber 31 through an inlet port 34 by the rearward movement of diaphragm 40. During the rearward stroke of piston 70, poppet valve 80 is reseated and vacuum pressure is reestablished within the vacuum chamber.
