    摘要: Disclosed is an apparatus, method and system comprising one or more devices capable of modulating fluid flow, the fluid being a liquid or a gas resulting in a pressure fluctuation in a fluid flowing within a flow channel, comprising: a flow modulating device that acts as a servo valve such that the device comprises a shaft and a moveable actuator that slides along the shaft, wherein the shaft and the actuator are positioned at any angle within a principal fluid flow channel such that the fluid flows through the principal fluid flow channel. The fluid flowing within the principal fluid flow channel is selectively reversible and the fluid is connected to both an inner pilot flow channel and the principal fluid flow channel wherein the flow modulating device includes a particulate barrier system having at least one seal system comprising an upper outer seal and a lower outer seal prohibiting fluid particulates from entering the inner pilot flow channel and also includes an upper inner seal and a lower inner seal that further prohibit residual particulates from reaching any mating surface between the shaft of the flow modulating device and the upper seal, the upper inner seal, the lower outer seal, and the lower inner seal. The particulate barrier system operates in a fluid flow field wherein the fluid can flow in any direction and utilizes a sealing system wherein an upper outer seal and a lower outer seal prohibit particulates from reaching the respective surfaces of an upper inner seal and lower inner seal of the flow modulating device. An upper inner seal and lower inner seal further prohibit residual particulates from reaching surfaces between the seal and that of the shaft of the flow modulating device.

    摘要: A device has been disclosed that may include a spool valve including a body having a first connector and a second connector and a spool movable relative to the body for controlling flow between the first connector and the second connector. The reversible flow control assembly further may include a pilot valve device developing a single pressure command in the form of a fluid at a command pressure. The spool valve may be responsive to the single pressure command developed in said pilot valve device to control flow between the first connector and the second connector without regard to the direction of flow. The majority of axial forces acting on the spool to position the spool relative to the body when fluid is flowing through the valve may be fluid forces.

    摘要: A fluid device driven solely by input fluid to reciprocate a driven member in the device. The device is readily attached to a normal or special fluid supply system. The device can produce a pulsating fluid output that may be used for cleaning, especially for cleaning around and between teeth, as well as for cleaning and massaging gums. The device includes a main fluid flow path between the inlet and the outlet to drive an actuating apparatus and to transfer most of the input fluid out through the outlet. The actuating apparatus includes a driven member (66), a control system, and a drive system. The drive system includes a fluid drive port and a biasing system (88) for providing the driving force to reciprocally drive the driven member (66) and for aiding cyclic movement of the driven member. The biasing system may be a compression air chamber (88) and the control system may be a drip valve system (79).
