  • Publication number: 20120000935
    Abstract: A self-contained, hand-held spray dispensing device includes an internal source of pressurized fluid that exerts a motive force on a pair of liquid ejecting elements to cause each to eject a liquid into a discharge line. The liquids remain separated until each exits its discharge port. A pressurized fluid is directed over the outlet ends of the discharge line beginning before a flow interrupter in the discharge line is opened to permit flow therethrough and ceasing after liquid flow is terminated. The pressurized fluid flow over the outlet of the discharge line aerosolizes liquids emanating from the outlet ends. The liquid ejecting element is connected to a force transmitting yoke. The yoke responds to pressurized fluid from the source to generate the motive force on the ejecting element.

    Abstract: The subject invention is a system for dispensing a controlled amount of fluid product from a dispensing container which includes a pneumatically driven dispensing actuator. This actuator includes a dispensing cylinder and a movable dispensing piston. The dispensing piston is movable under pneumatic pressure within the cylinder, the cylinder including a volume of hydraulic fluid under the pneumatic pressure acting against the dispensing piston to selectively prevent movement of the dispensing piston. The invention further includes a means for selectively reducing the volume of the hydraulic fluid in the dispensing cylinder to allow the controlled movement of the dispensing piston. The controlled movement of the dispensing piston causes controlled displacement of the fluid product from the dispensing container. Advantageously, with the subject invention, a force may be generated and applied to a plunger, which can be accurately controlled.

    Abstract: A drive characteristic and durability of a liquid supply device having a flexible pump member such as a bellows are improved. A drive pump in the liquid supply device has a bellows as the pump member that is elastically deformed axially by a drive rod. A drive pump chamber and a communication chamber are formed by the bellows and the housing, and the communication chamber and the drive pump chamber are partitioned by the orifice member. At a drive operation time of the drive rod, the through hole is blocked by the valve member, and a liquid flows in between the communication chamber and the drive pump chamber via a communication gap formed between the orifice member and an inner circumferential face of the housing.

  • Publication number: 20110240672
    Abstract: This invention provides a chemical supply system for supplying chemical solution from a chemical tank. The chemical supply system includes a chemical supply pump, a pressure adjuster configured to suction the chemical solution into the pump chamber by setting the pressure of working gas to a suction pressure, a switching controller configured to switch the suction-side opening-closing valve to the open state for starting to fill the pump chamber with the chemical solution, a pressure detector configured to detect at least one of a gas pressure in a space connected to the working chamber and a gas pressure in the working chamber when the suction-side opening-closing valve is switched to the open state and starts an inflow of the chemical solution to the pump chamber, and a suction controller configured to control the suction pressure applied to the working chamber by the pressure adjuster, based on a detection result of the pressure detector.

  • Patent number: 7997457
    Abstract: A system is disclosed for delivering hyper-concentrated chemicals in a ready to use non-concentrated state. The present invention affords users with the ability to dispense the hyper-concentrated chemicals in a safe electrical free environment as the system operates from fluid force. The present invention may work off a water supply being used as the primary power supply that is also used to dilute the hyper-concentrated chemical. The present invention may be configured for use in any number of environments, such as refineries, off-shore platforms, food processing facilities, agriculture facilities, and the like.

  • Publication number: 20110132934
    Abstract: Here presented is a hydraulic dispensing apparatus that includes a main frame as a base 1, said frame 1 having a reservoir 4 for liquids for dispensing joined to a cylinder 2 and piston 3 structure fastened to it. The frame 1 provides a hose connector 8 to accept the intake of hydraulic fluids into the cylinder 2 and piston 3 structures; this would provide hydraulic force to actuate the piston 3. Said cylinder 2 has a hose connector 12 to accept the intake of liquids for dispensing from the reservoir 4. This connection allows the cylinder 2 to be refilled without having one of the ends of the cylinder 2 opened. A piston rod 7, secured to the piston 3 and movable therewith, allows for the piston 3 to be retracted to its initial position either manually or with the use of a mechanical device. Retracting the piston 3 to its initial position creates a vacuum effect that forces the liquids for dispensing from the reservoir 4 into the cylinder 2.

  • Patent number: 7905375
    Abstract: A device for dispensing flowable materials to low locations without the user being required to bend over or kneel down during dispensing provides relief from back strain or other injuries. The device includes a cylinder having a piston mounted therein which reciprocates between forward ejecting and return directions. A driven rod, connected to the piston, extends through a front wall of the cylinder. Upon actuation, a trigger mechanism supplies a pressure medium within the cylinder for displacing the piston in the forward ejecting direction to dispense flowable material from the dispensing device. The trigger mechanism is oriented to enable the user to hold the dispensing device like a suitcase and is spaced a sufficient distance from where the flowable material is dispensed to enable a user to remain standing erect while dispensing to low areas such as where a floor and wall meet.

  • Publication number: 20100230436
    Abstract: A system for monitoring and controlling the delivery of CO2 from a bulk storage tank to at least one gas-driven pump is disclosed. By monitoring certain conditions, the flow of CO2 can be quickly and easily terminated if necessary, thereby reducing or eliminating undesirable consequences of CO2 gas flow in abnormal operational scenarios. The invention is particularly well suited for deployment in conjunction with beverage dispensing machines and can be configured to shut down the flow of CO2 if a drop in pressure occurs due to a leak in the system or if a syrup delivery system runs out of product.
