摘要： A multi-stroke air cylinder providing a precisely directed and controlled stroke in the face of lateral, torsional and tilting loads on a tooling plate. The multi-stroke cylinder utilizes a plurality of mechanically linked pneumatic or hydraulic pistons having different stroke lengths that can be added together in any combination, allowing the user to select any stroke length up to a predetermined, total combined stroke length, in increments equal to the stroke length of the smallest cylinder. The multi-stroke cylinder includes a head assembly having a fluid inlet for introducing fluid to the cylinder at a first pressure. The cylinder also includes a first positioning system having a plurality of pistons capable of moving a piston rod away from the first positioning system, and a second positioning system located between the head assembly and the first positioning system. The second positioning system comprises a plurality of movable pistons for displacing the piston rod a preselected distance and at least one elongated fluid supply member secured to a respective one of the pistons of the second positioning system for introducing a fluid between adjacent pistons. When a plurality of fluid supply members are used in the second positioning system, they are concentrically arranged and are at least partially coextensive with one another.

摘要： A housing (10, 12, 14) has first and second flexible membranes (32, 42) dividing it into two sealed chambers plus a third chamber from which the movable member (38) projects. Each membrane co-operates with a respective cup (40, 50) and return springs (54, 56) tend to urge both cups away from an end wall (26). The two cups are interconnected by a single piece member (58) which is inextensible but which can readily be bent in two to enable the cups to come into contact with one another. Each sealed chamber can individually be selectively connected to a source of reduced pressure via a respective orifice or pipe fitting (30, 28). The position of the movable member (38) can thus be changed.
摘要翻译：壳体（10,12,14）具有将其分成两个密封腔室和第三腔室的第一和第二柔性膜（32,42），可移动构件（38）从该腔室伸出。每个膜与相应的杯（40,50）协作，并且复位弹簧（54,56）倾向于将两个杯推离端壁（26）。两个杯子是通过不可伸长的单件构件（58）相互连接的，但是它们可以容易地弯曲成两个，以使杯子彼此接触。每个密封腔室可以分别通过相应的孔或管接头（30,28）选择性地连接到减压源。因此可以改变可动构件（38）的位置。

摘要： A digital positioner for remote actuation of a control valve includes a double-acting actuating piston connected to the control valve and a plurality of fluid-responsive stop means disposed to either side of the actuating piston. A plurality of remotely controlled pilot valves are operatively connected to respectively control the actuating piston and selected ones of the stop means. The system is especially adapted for remotely controlling hydraulic systems having a control valve for modulated control of the system for different speeds of the system.

摘要： This is a pneumatic actuator for a liquid delivery truck. The actuator can be added to an existing set stop valve without reconfiguring the piping. The same actuator can be used to upgrade several sizes of a rising stem valve. It provides the ability to open and close the valve as well as perform an adjustable low flow function. It works with existing relay logic from a cab mounted or meter mounted electronic preset. The actuator can be used with either an electric or pneumatic switch for setting the low flow position.

摘要： An indexing apparatus (10) having a pair of concentric cylinders (12, 14) with the outer concentric cylinder (12) being fixed against longitudinal movement and the inner cylinder (14) mounted for reciprocal movement relative to the fixed outer cylinder (12). A single ram piston (16) is mounted within the inner cylinder (14) and has a piston rod (18) connected to a member (29) for positioning at four predetermined positions. A shock absorber (24) is carried by the outer fixed cylinder (12) and engages stop plates or abutments (20, 28) carried by the inner cylinder (14) for activation of the shock absorber (24). A pair of guide rods (42) prevent rotational movement of inner cylinder (14) relative to the inner cylinder (12) and maintain the shock absorber (24) in axial alignment with the end abutments (20, 28). In one embodiment (FIGS. 9-11), guide rods (41A, 42A) have fluid passages (49A, 53A) in fluid communication with fixed ports (P5, P6) in the outer fixed cylinder (12A) for the supply of fluid to piston chambers (32A, 36A) in the reciprocable inner cylinder (14A).
