    • An on-board diagnostic system for an evaporative emission control system of an internal combustion engine powered vehicle employs a positive displacement reciprocating pump to create in evaporative emission space a pressure that differs significantly from ambient atmospheric pressure. The pump is powered by using engine intake manifold vacuum to force an intake stroke during which both an internal spring is increasingly compressed and a charge of ambient atmospheric air is created in an air pumping chamber space. Vacuum is then removed, and the spring relaxes to force a compression stroke wherein a portion of the air charge is forced into the evaporative emission space. The rate at which the pump reciprocates to alternately execute intake and compression strokes indicates the pressure and flow through a leak in the evaporative emission space. Detection of this rate serves as a measurement of leakage for the purpose of distinguishing integrity of the evaporative emission space from non-integrity.
    • 用于内燃机动力车辆的蒸发排放控制系统的车载诊断系统采用正排量往复泵,以在蒸发发射空间中产生与环境大气压力显着不同的压力。 泵通过使用发动机进气歧管真空来驱动,以迫使进气冲程,其中内部弹簧越来越多地被压缩,并且在空气泵送空间中产生周围大气的空气。 然后除去真空,并且弹簧松弛以迫使压缩冲程,其中空气充注的一部分被迫进入蒸发发射空间。 泵往复运动以交替执行进气和压缩冲程的速率表示压力和通过蒸发发射空间中的泄漏的流量。 为了区分蒸发排放空间的完整性和非完整性,该速率的检测用作泄漏的测量。

    • A vacuum powered pump includes a spring biased piston or diaphragm in a vacuum chamber coupled to a source of vacuum. When vacuum is applied to the vacuum chamber, the piston or diaphragm is moved in a first direction against the spring. A delayed action valve is coupled to the vacuum chamber to allow ambient air to enter the chamber only after the piston or diaphragm has been moved a substantial distance in the first direction. When the delayed action valve opens, air enters the vacuum chamber and the force of the entering air together with the bias of the spring propels the piston or diaphragm in a second direction opposite the first direction. The delayed action valve automatically closes and the process repeats so long as a vacuum source is coupled to the vacuum chamber. The reciprocal movement of the piston or diaphragm effects a pulsatile pumping of fluid through a fluid chamber having at least one check valve.
    • 真空动力泵包括与真空源联接的真空室中的弹簧偏压活塞或隔膜。 当真空被施加到真空室时,活塞或隔膜相对于弹簧在第一方向上移动。 延迟动作阀联接到真空室以允许环境空气仅在活塞或隔膜已经在第一方向上移动相当大的距离之后才进入腔室。 当延迟动作阀打开时,空气进入真空室,并且进入空气的力与弹簧的偏压一起沿与第一方向相反的第二方向推动活塞或隔膜。 延迟动作阀自动关闭,并且只要真空源耦合到真空室,该过程就重复。 活塞或隔膜的往复运动使液体通过具有至少一个止回阀的流体室脉动泵送。

    • A vacuum-operated liquid pump includes a pumping member and a housing defining a pump chamber in which the pumping member moves along suction inlet and pressure discharge strokes. The pumping member divides the pumping chamber into a liquid space on one side of the pumping member and a gas space on the other side of the pumping member. A liquid-supply communicates with the liquid space for responding to movement of the pumping member along its suction inlet stroke to deliver liquid to the liquid space. A liquid discharge also communicates with the liquid space for responding to movement of the pumping member along its pressure discharge stroke to discharge liquid out of the liquid space. A passage communicates with the gas space for placing the latter in communication with a source of vacuum, while a valve cooperates with this passage for alternately placing the latter in communication with the source of vacuum and in communication with the outer atmosphere. This valve is operatively connected with the pumping member to be operated thereby for placing the passage in communication with the source of vacuum when the pumping member reaches the end of its pressure discharge stroke and for placing the passage in communication with the outer atmosphere when the pumping member reaches the end of its suction inlet stroke.

    • 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.

    • A reciprocating fluid motor, notably for operating a pump comprising an enclosure divided into two pressure chambers by a movable wall, said movable wall experiencing a forward stroke and a return stroke and being resiliently urged towards the return position, a control device responsive to the position of the movable wall controlling a distributing valve to alternately communicate one of said pressure chambers with a high pressure equalling the pressure residing at all times in the other chamber, and with a lower pressure. In this motor the control device and the distributing valve are mounted within the thickness of the movable wall, and the control device is a fluidic flip-flop. If air is selected as energizing fluid for the motor, the high and low pressures can be the atmospheric pressure and the vacuum created in the intake manifold of an engine respectively.
