  • Patent number: 9140469
    Abstract: A service valve assembly that is designed to minimize leakage by reducing the number of leakage paths from the valve assembly. In addition, the service valve assembly is designed to permit connection to many different refrigeration systems and has higher flow capacity. The valve assembly is engageable by current servicing tools so that purchase of new service tools is not required. In the valve assembly, the service connection is designed as part of the shut-off valve and communicates with the condenser side port. Therefore, initial processing through the condenser side port and subsequent processing through the evaporation side port occur through the combined service connection and shut-off valve structure. Once installed, the described valve assembly has one leak path versus two leak paths in known valve assemblies.

    Abstract: A valve assembly includes a body structure having a proximal inlet tube and a distal outlet tube separated by a valve cylinder portion, a flow control valve situated in the valve cylinder portion, the flow control valve including a valve plug and an actuator shaft, and an actuation control pivotally mounted to the body structure, wherein rotational movement of the actuation control exerts an axial force against the actuator shaft to move the valve plug through the valve cylinder portion and open fluid communication between the proximal inlet tube and the distal outlet tube. A bead seating system includes means for establishing fluid communication between a container of pressurized fluid and a valve assembly, means for transferring rotational movement of a actuation control pivotally mounted on the valve assembly into an axial force, means for establishing fluid communication between the container and a bead seating tool via the valve assembly.

    Abstract: A plug valve including a valve body having an inlet port, an outlet port and a central chamber extending between the inlet port and the outlet port. The valve also includes an inlet seal segment within the central chamber and includes a bore extending therethrough and aligned with the inlet port. An outlet seal segment is disposed within the central chamber having a bore extending therethrough and aligned with the outlet port. A plug member is disposed in the central chamber and is moveable between an open position, to facilitate fluid flow through the plug valve, and a closed position, to block fluid flow through the plug valve. First and second side segments are disposed between and interlocked to the inlet and outlet seal segments to encircle the plug member. The side segments are tensioned to preload the seal segments against the plug member to prevent the flow of fluid between the seal segments and the plug member.

  • Patent number: 8631822
    Abstract: A dual-flow valve includes an inner valve body defining a first flow path and an outer valve body circumscribing the inner valve body. The outer valve body and the inner valve body define a second flow path. The dual-flow valve includes a valve element disposed across the first flow path and the second flow path. The valve element has a first passage for selective flow alignment with the first flow path and a second passage for selective flow alignment with the second flow path. A dual flow swivel includes an upper and lower swivel body, with the lower body adapted to rotate relative to the upper body. Two separate flow paths extend through the swivel bodies allowing upwardly and downwardly directed flows through the swivel bodies.

  • Patent number: 8613276
    Abstract: A duel fuel gas control valve controls the supply of gas (e.g., natural gas or liquid propane gas) to a gas grill. The duel fuel gas control valve is structured to control either natural or LP gas flow at the desired operating characteristics based on conventional gas supply characteristics and gas grill requirements. A restrictor mechanism, when in first and second configurations, respectively, restricts movement of the valve core to a first predetermined range for a first mode of operation (first type of gas supply) and to a second predetermined range for a second mode of operation (second type of gas supply).

    Abstract: A rotating gate valve can be used to shear cables or tubing as it closes to obstruct flow. In embodiments, a valve body can have a flow passage and a lateral bore that is transverse to the flow passage. The gate can have a generally cylindrical shape and can rotate about the axis of the gate as it moves laterally to close a flow passage. The lateral and rotational movement can shear articles such as, for example, cables and tubing that extend through the flow passage.

    Abstract: A collection valve for use in a water reclamation system is provided. The collection valve comprises (i) a drain pipe connectable to a drain line in which gray water flows, the drain pipe comprising an inlet pipe, a medial pipe, and an outlet pipe; the medial pipe having a first opening rotatable from a first position to a second position; (ii) a valve plug pipe, surrounding the medial pipe, having an second opening; and (iii) an actuator assembly for rotating the medial pipe between the first and second positions. Rotating the medial pipe to the first position causes the first opening to be in alignment with the second opening causing gray water to drain into a tank. Rotating the medial pipe to the second position misaligns the first and second opening causing fluid passing through the medial pipe or drain to a sewer or septic tank.

  • Publication number: 20130233414
    Abstract: A quiescent zone fluid filter. A reservoir communicates via upstream and downstream communication ports with a fluid flow tube. At the upstream communication port, liquid flowing in the fluid flow tube enters a quiescent zone of the reservoir, whereupon particles therein descend. The liquid then rejoins the fluid flow tube at the downstream communication port free of particles therein. The quiescent zone fluid filter is advantageously implemented within a fluid flow control valve, as for example at the valve barrel of a barrel valve.
