Valve In Each Inlet Patents (Class 137/606)
  • Publication number: 20020059958
    Abstract: A flow cell (1) has at least two inlet channels (6 to 9), each connectable with a reservoir (10 to 13) and controllable by means of valves (14 to 17) and ending in an inlet chamber (5). Each of the two ends (21, 22) of the inlet chamber (5) is connected with the discharge channel (18) by means of an outlet channel (19, 20). Thus, the old fluid remaining in the chamber is displaced into the discharge channel (18) by the newly supplied fluid. The dead time until the passing of the pure new fluid is short.

    Abstract: A system and method for connecting a secondary source of a medical gas to a medical gas supply system which enables uninterrupted gas supply without backfeeding. A control panel (10) is connected in the system fluidly between primary supply sources (44, 45, 46) holding types of medical gas and gas outlets (54, 55, 56) for the delivery of the respective types of medical gas to devices in a medical facility. For each gas type the control panel houses a respective shut off valve (24, 25, 26). The shut-off valve may be closed to isolate the upstream source from the downstream components. The control panel also houses for each gas type a respective secondary gas inlet port (68, 69, 70). The inlet ports have connections specific to the type of gas which may be received therethrough. Check valves are provided to enable fluid flow only into the inlet ports. A removable cover or face (11) is normally installed on the control panel.

  • Patent number: 6298875
    Abstract: A slide valve faucet handle operates when a user arcuately pushes or pulls the handle back and forth in one arcuate axis. A knob atop the slide valve is pushed away from the user in an arcuate fashion to increase flow or pulled toward the user to reduce or shut off flow. The slide valve includes an escutcheon/valve housing at the bottom with a manually graspable knob at the top attached to a movable cover member. The cover member, which is basically hemispherical, has a section removed at an angle to permit the movable cover to advance forward over the escutcheon/valve housing. With the knob in the upright position, the valve is closed. With the knob tilted fully back in a position of use, the slide valve is in the full open position. Intermediate positions regulate flow in a continuous linear manner as expected. There is no spring return, so the slide valve remains open where adjusted along the arcuate axis.

  • Patent number: 6240943
    Abstract: The present invention reveals a gas mixing device which maintains constant gas ratios under both steady state and intermittent flow conditions, and reduces mixture errors inherent with multiple gauges by providing only one pressure gauge to read the inlet pressure at each inlet port. To accomplish its purpose, the device comprises a chamber defined by two opposing hollow core pistons, a downstream control valve, and an upstream delay valve. The control valve, assisted by one piston, opens and closes in response to the upper and lower operating pressure limits of a receiver. The delay valve, assisted by the other piston, closes after the control valve closes and opens abruptly only after a significant drop in pressure within the chamber, the result of the control valve having suddenly opened wide. A single pressure measuring assembly, rotatably mounted to the gas mixing device, communicates with each inlet port.

  • Patent number: 6220266
    Abstract: A faucet assembly including dual handles whose position indicates, both tactilely and visually, the volume and exit temperature of the water flowing from hot and cold water valves to a faucet outlet. Such indication is achieved by the mounting and controlled movement of the handles, by their configuration and perimeter, by surface exposure, and by their individual connections to hot and cold water valves. The proximity of the handles and their controlled movement enables the handles to be manipulated simultaneously by a single hand of the user without pinching the fingers. The handles are mounted to conceal their mountings and their connections to the valves and are thus the only parts of the faucet assembly visible to a user thereby enhancing the appearance of the installation. Further, the faucet assembly reduces plumbing costs and is universally adaptable to both rotary and linear water valves in a wide variety of bath and kitchen installations.

  • Patent number: 5979775
    Abstract: A bathing water pre-mix system, for attaching to an existing plumbing system and supplying temperature regulated water to a user. A mixing tank has a hot water inlet and cold water inlet that is attached to the existing plumbing system. The mixing tank has at least one outlet for dispensing water from the mixing tank, preferrably through a shower head. A desired temperature control allows the user to set a desired water temperature. A pair of solenoid valves control water flow at the hot water inlet and cold water inlet in an attempt at achieving the desired water temperature within the mixing tank. A water level indicator informs the user about the water level within the mixing tank. When a sufficient volume of water is present in the mixing tank at the desired temperature, water flow into the tank is halted, and the water in the mixing tank is dispensed to the user through the outlet.

  • Patent number: 5950675
    Abstract: An apparatus for mixing and feeding plural gases flowing at different mass flow rates and having different molecular weights includes a plurality of gas feed lines connected to a mixing region having an outlet for feeding a mixture of the gases to a semiconductor production apparatus. The gas feed line carrying the lowest-flow-rate gas is connected to the mixing region at a location farther from the outlet than where any other feed line is connected to the mixing region. Feed lines carrying gases other than the lowest-flow-rate gas are connected to the mixing region according to (1) the relative mass flow rates of the gases carried by the lines (2) the relative molecular weights of the gases carried by the lines or (3) the product of the respective gas flow rates and molecular weights of the gases. At least the line carrying the lowest-flow-rate gas is provided with an apparatus for increasing the velocity of the gas flowing therein prior to entry of the gas into the mixing region.

  • Patent number: 5950674
    Abstract: A fluid control valve arrangement allowing very complex valve interconnection schemes to be implemented in a small volume is disclosed. The fluid control valve arrangement utilizes seat plates positioned above and below a block to allow creation of three layers of material between valve elements on opposite sides of the block. Since there are three layers of material between blister valve elements on opposite sides of the block, there are two interfaces on separate levels from those levels contacting valve membranes and blister recesses upon which to form interconnection channels. Because each side of the block has one layer allocated for blisters and another allocated for formation of interconnection channels, very complex valve interconnection schemes may be implemented in a small volume.
