摘要： A fluid flow control system serving as an inflow port from a fluid reservoir (R) to the interior of a production pipe (S) is in the form of a housing (3b, 3c, 3d, 3e, 3f, 3g, 3h, 3i, 3j, 3k, 3l). The housing has a primary flow path (18) and a secondary flow path (19). The secondary flow path is in fluid communication with a chamber (B) in which is arranged an actuator (5) for a valve device (4), the valve device arranged to open and close the primary flow path. At least one flow restrictor (1,2) is arranged in the secondary flow path, the flow restrictor arranged to provide a pressure to chamber (B) sufficient to actuate the valve to an open position when the fluid flowing through the secondary flow path is oil, and a pressure sufficient to actuate the valve to a closed position when the fluid has a viscosity and/or density less than oil.

摘要： A flow regulator for regulating a flow rate of water within at least a section of a water system, such as an irrigation system, includes a base member and piston member. The piston member is movable relative to the base member and includes at least one notch through which water can flow when passing through the flow regulator. Movement of the piston member towards and away from the base member, respectively, decreases and increases an area of the notch through which water can flow. An orifice member detachably coupled to the piston member and having an orifice member aperture through which all water flowing through the flow regulator must pass limits the cross-sectional area of an interior water passage within the piston member.

摘要： A hybrid pressure and flowguage regulator apparatus includes a regulator body, an inlet, and an outlet assembly. The outlet assembly includes a first orifice of a first size, a second orifice of a second size that is larger than the first size, and a mechanism that automatically moves the first orifice between a first position and a second position. When the first orifice is in the first position, the flow of gas passes through both the first orifice and second orifice. When the first orifice is in the second position, the flow of gas bypasses the first orifice and flows through the second orifice with a specific flow rate or a second pressure that is less than the first pressure. The apparatus may also include a gauge that provides a visual indication of both the specific flow rate and the second pressure.

摘要： The invention is directed to a method to improve accuracy of a meter. The method first contemplates introducing a desired fluid into a valve assembly having an external casing with an inlet, outlet and interior side forming a chamber. Next, a desired fluid contacts a toggle stopper having a shaft, plate, and guides. A calibrated spring positioned around the shaft in contact with the plate assesses if the desired fluid meets a predetermined pressure. If the fluid meets this threshold, the calibrated spring compresses thereby toggling plate within the chamber to allow desired fluid to enter the chamber. Should the total pressure of the desired fluid and/or an undesired fluid create a pressure that fails to meet the predetermined pressure, the calibrated spring expands to seal the valve assembly. Upon such seal, there is an equalizing of both the desired and undesired fluids to the same pressure by decreasing the volume of the undesired fluid, causing the calibrated spring to compress and reopen.

摘要： An oil return mechanism includes a base, a control switch, a first blocking ball mounted in the base, an elastic member mounted between the first blocking ball and the base. The base has a liquid storing cavity, a liquid returning cavity, a communicating cavity, a first communicating opening communicating between the liquid returning cavity and the communicating cavity, and a second communicating opening communicating between the communicating cavity and the liquid storing cavity. The present invention can regulate a speed of a fluid flowing from the liquid returning cavity to the communicating cavity, and has the advantages of simple structure and great reduction of cost.

摘要： The present disclosure provides a flow regulator capable of regulating flow resistance of a fluid by adjusting helical pitch of the flow regulator. The flow regulator comprises: a channel, a rod, and a helical coil. The channel has a fluid inlet and a fluid outlet for a fluid flowing in and out of the flow regulator, respectively. The rod has a fore end and a rear end opposite to each other. The fore end is inside the channel, and the rear end is closer to the fluid outlet than the fluid inlet. The helical coil winds around the rod, and the helical pitch of the helical coil is adjustable for regulating flow resistance of the fluid. The channel further has a narrowed section where part of the helical coil located therein substantially occupies an annular space between the rod and an inner wall of the channel.

摘要： A PCV valve that also monitors the flow of gases produced by use of a turbocharger. A spring biased plunger member is used to restrict and meter the flow of gases through the PCV valve. A nozzle member with a Venturi throat is used to allow back flow caused by use of a turbocharger. The nozzle member can be part of a module including a passageway member that can be closed by the plunger member.

摘要： A main stage in-line pressure control cartridge. The cartridge selectively controls flow in-line in the same direction as opposed to directing flow at a 90 degree angle like other cartridges. A tubular poppet can be mounted into a body and has a sliding control sleeve that can expose radial holes in the poppet to an open position and to seal the radial holes in a closed position. The cartridge can be configured in numerous ways in order to serve many functions, such as a pressure relief valve, a counterbalance valve, and a flow control valve. The cartridge can also be configured to allow or prevent reverse flow.

摘要： An annular valve seat is projected radially inward from a passage wall. A valve element is located on the upstream side of the valve seat. A spring biases the valve element toward the upstream side. The valve element has a through hole to pass fluid between the upstream side and the downstream side when the valve element is seated on the valve seat. The valve element switches between a large opening state, in which the valve element is lifted from the valve seat to pass fluid around an outer circumferential periphery of the valve element and to pass through the through hole, and a small opening state, in which the valve element is seated on the valve seat to pass fluid through the through hole. The valve element is supported and slidable on a guide surface, which is formed on the passage wall, at the outer circumferential periphery.
