    Abstract: A dispense tap for a frozen beverage machine has a transition section defining a tapered bore with an inlet for frozen beverage from a freeze barrel of the machine and an outlet for frozen beverage controlled by a valve operable by a handle. The handle is rotatable to allow frozen beverage to flow from the transition section through a dispense cavity in the valve for exiting the tap. The outlet has a cross-section greater than the cross-section of the inlet which prevents ice conglomerating and forming a plug in the bore of the transition section.

  • Patent number: 7967023
    Abstract: A control valve for use in a liquid-carrying system, such as a heating or cooling system, containing a differential pressure governor which keeps the differential pressure between the inlet and the outlet constant. The control valve also includes an arrangement for setting and adjusting the maximum flow of liquid through the valve. This arrangement comprises a flow valve having two cooperating valve members (4 and 6), which are arranged in the flow path and are constructed as two concentric rings, each of which has a recess extending about 180 degrees in the circumferential direction. The outer ring (4) is stationary relative to the valve housing, while the inner ring (6) may be displaced in the circumferential direction by means of a rotatable handle, whereby a greater or smaller overlap between the recesses may be provided. The maximum flow amount may hereby be set manually.

  • Patent number: 7967005
    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).

  • Publication number: 20100213400
    Abstract: The invention relates to a valve comprising a housing and a closing member arranged in the housing, from which member a shaft protrudes via which the closing member is rotatable in the housing. In order to provide a working and easy-to-use valve, the closing member comprises a sector closing the opening, a flexible sector having a thinner wall than the closing sector, a guiding sector having the same radius (R) as the inner surface of the housing wall, and an open sector.

  • Patent number: 7690397
    Abstract: A valve includes a body having an interior and defining at least one inlet passageway and discharge passageway. The valve also includes a flow diverter disposed within the body between the inlet and discharge passageways to receive a fluid from the inlet passageway in an inlet direction. The diverter is adapted to discharge the fluid to at least one discharge passageway in a direction that differs from the inlet direction. The diverter is rotatable to vary the discharge direction. According to one embodiment, the discharge direction is substantially perpendicular to the inlet direction.

  • Patent number: 7546851
    Abstract: A change valve for an air compressor is combined with the vent tube of an air compressor, including a connector, a valve base, a valve body, an anti-leak gasket, a sleeve and a button. The valve base has at least two connect tubes, with a guide tube connected to each of the connect tubes. The button can be turned to rotate the valve base together with the valve body, so the vent hole of the valve body can be aligned to the air hole of either of the two connect tubes. If the air compressor operates, compresses air may flow in the valve body via the air hole into the guide tube via the vent hole of the connect tubes, and finally into an object. In this way, interchanging the position of the vent hole of the valve body enables the change valve connected to objects having different air valves.
