    Abstract: Embodiments of a valve device that reduces noise and vibration that may occur during low flow conditions in fluid couplings (e.g., valves and flow regulators). These embodiments utilize a plug and seat arrangement with geometry to prevent pressure differentials that cause the plug element to open and close in a cyclic pattern. In one embodiment, the valve device includes a seat element with an aperture and a plug element with a boss that extends into the aperture when the plug element contacts the seat element. The boss has an outer surface that forms a gap, which defines an annular area proximate the point of contact between the seat element and the plug element that is sized to reduce Venturi flow effects that cause the cyclic pattern to occur.

  • Patent number: 7950384
    Abstract: Cooking appliance having an external and control panel equipped with one or more regulating valves, where the rotary regulator organ is equipped with various peripheral openings for supplying a flow Q. According to two embodiments of the cooking appliance, for the supply of one or another type of gas, NG or LPG, either the control knob or a bezel disk in the external panel are interchangeable on the appliance, being chosen between two different available units, one and the other permitting two different angular position limits A2, A3 of the regulator organ for the supply of a constant flow Qmin through one or another opening with calibrated sections, respectively for NG or LP gas. An appendix in the control knob guided in a slide groove on the control panel of the appliance, or a tongue on the bezel disk stopping the rotation of the control knob, determines the travel limit A2 for the supply of Qmin of NG.

  • Patent number: 7878194
    Abstract: An inhaler has a cap body for defining a flow path and having first and second air inhalation openings for introducing outside air into the flow path from the outside; an air inhalation valve for opening and closing the first air inhalation opening by using the difference in pressure between the flow path and the outside; and a shielding section capable of selectively shielding either of the first and second air inhalation openings. The inhaler is configured to be switchable between two states that are a first state where the second air inhalation opening is shielded by the shielding section and outside air can be introduced through the first air inhalation opening by using the pressure difference and a second state where the first air inhalation opening is shielded by the shielding section and communication between the flow path and the outside through the second air inhalation opening is constantly maintained.

  • Publication number: 20100278951
    Abstract: This manifold comprises a stack formed by at least a plurality of tubular modules and a first support, and at least one tie for compressing the stack in a configuration in which central internal volumes of the various modules are in mutual communication, with adjacent parts of the stack overlapping in leaktight manner, and in which the relative position of two adjacent modules is stationary. The tie may be fastened in rotation about its longitudinal axis and in translation parallel to said axis, relative to the first support. The tie is equipped with a clamping nut that, in the tightened position, exerts a compression force on the stack of modules and on the first support.

  • Patent number: 7806133
    Abstract: A controller and method of using same are disclosed. Preferably, the controller includes a pilot cartridge housing supporting an invertible pilot cartridge assembly (“cartridge”). The cartridge preferably includes a cartridge body supporting a number of pneumatic seals adjacent the housing, wherein at least two of the seals are diaphragms. The cartridge preferably provides a first pilot activation feature and an opposing second pilot activation feature. The operating mode of the cartridge is determined by a selected orientation of the first pilot activation feature relative to the housing; and preferably the method of operating the controller includes the steps of: selecting an orientation of the first pilot activation feature relative to the housing; setting a span control mechanism to a neutral position relative to the housing; adjusting a float communicating with the cartridge to a neutral position; and adjusting said span control mechanism to determine a response type of said cartridge.

  • Patent number: 7793678
    Abstract: A converter valve allows product dispenser operator to change from a first fluid source to a second fluid source without fluid crossover. The converter valve includes a first port in fluid communication with a dispense point, a second port in fluid communication with a first fluid source having a first fluid, and a third port is in fluid communication with a second fluid source having a second fluid. The converter valve includes a passage between the first and second ports, and a plug in fluid communication with third port. The second and third ports of the converter valve are disposed symmetrically about the first port, and, accordingly, the converter valve is rotatable about the first port. As such, the converter valve delivers the first fluid to the dispense point, and delivers the second fluid through the passage to the dispense point when the converter valve is rotated.

  • Patent number: 7699072
    Abstract: A device for regulating the delivery pressure of gases includes a valve unit having at least one valve seat and a respective closure element displaceable along an axis with respect to the valve seat which is controlled by a diaphragm. The device further includes a first spring which acts on the diaphragm in order to subject it to a preselected resilient load. A second spring is selectively activated to exert an additional resilient load on the diaphragm. The device includes a handle associated with the first and second springs in order to impose selectively the desired delivery pressure value, between a minimum value and a maximum value of pre-calibration, the pressure value being proportionally correlated with a predetermined resilient load exerted on the diaphragm.

  • Publication number: 20090020164
    Abstract: An Integrated and Detachable Float-valve-mounted Suction Plug is disclosed. The float valve having an integrated suction plug provides dual functionality—the functionality of a conventional diverter valve, as well as the functionality to plug the skimmer assembly pump suction port. The detachable float-valve-mounted suction plug is configured to snap over the top of a conventional diverter device in order to add the skimmer assembly suction port plug functionality. Both versions will eliminate the need for a pool cleaning person to carry a bag-full of tennis balls or plugs. Each device is designed to stay with or be incorporated within the diverter inside of the skimmer housing. Finally, both embodiments allow the plugging of the pump suction port by flipping over the diverter and then replacing the diverter inside of the skimmer housing.
