| 137614180 | One valve head carries other valve head | 8 |
| 20080271798 | GAS APPLIANCE - A coupling for attaching a canister to an appliance comprises a first connector on the canister comprising screw threads and a groove and a second connector on the appliance that comprises a slip ring. The slip ring retains the canister on the appliance. An appliance comprises a canister having screw threads. A coupling connects the canister to the appliance separate from the screw threads where the coupling locks the appliance to the canister without rotating the appliance relative to the canister. The coupling locks the appliance to the canister when the canister is moved axially relative to the appliance. A canister is provided that has a connector comprising a set of screw threads for attaching the canister to a first type of appliance, and a groove for attaching the canister to a second type of appliance. A method of connecting a canister to an appliance is also provided. | 11-06-2008 |
| 20090065077 | Double seat valve for separating media - A double seat valve for separating media includes a valve housing which has connectors for a first pipeline and a second pipeline, a first closing element and a first closing element seat which is assigned to the latter, where the first closing element is in seal-forming abutment, in its closed position, with the first closing element seat via at least one sealing element, and a second closing element which is spaced apart axially from the first closing element, and a second closing element seat which is assigned to the second closing element, where the second closing element is, in its closed position, in seal-forming abutment with the second closing element seat via at least one sealing element, where the two closing elements can be lifted independently of one another from their respective closing element seat, and where a leakage space is provided between the two closing elements. | 03-12-2009 |
| 20090139588 | TWO-STAGE VALVE FOR CONTROLLING FLUIDS - The present invention relates to a two-stage valve for controlling fluids, in particular a hydraulic fluid, The valve includes an actuating element, a pilot stage having a first valve seat and a first closing body, which is connected to the actuating element, and a main stage having a second valve seat and a second closing body. The second closing body is provided with a fastening region and a main region having a passage opening. The first valve seat is arranged at the passage opening. The second closing body is connected to the actuating element via the fastening region. The fastening region is designed elastically in such a way as to open the pilot stage by elastically deforming during actuation of the actuating element. | 06-04-2009 |
| 20120180888 | HIGH FLOW SERVICE VALVE - A high flow service valve is provided that does not rely on the use of a valve core. The high flow service valve allows a condensing unit to be evacuated and charged very quickly. The high flow service valve utilizes a second movable obturator positioned at least partially in the valve body having a first position wherein a charge passageway is fluidly connected to a charge port and a second position wherein the charge passageway is fluidly disconnected from the charge port. | 07-19-2012 |
| 20120291898 | Dosing Device and Dosing Method for Liquids - The invention relates to a dosing device having an inlet for a liquid to be delivered to a container as a dose, in particular a beverage. The device comprises a valve seat, a sealing element interacting with the valve seat and an outlet for the dose of the liquid. In order to reduce foam build-up upon delivering the liquid into the container, according to the invention the sealing element can be moved to a first and a second opening position, wherein, in the second opening position, the flow cross-section area between the valve seat and the sealing element is larger than in the first opening position. In addition, the invention relates to a dosing method comprising the supplying of a liquid to a valve which is moved to a first and second opening position. | 11-22-2012 |
| 20140311600 | Drive for Switching a Double Seat Valve - A double set valve capable of seat cleaning has a drive and control unit integrated together. The drive switches the valve, and includes two closing elements moveable independently of each other and enclose a leakage cavity. | 10-23-2014 |
| 20140326341 | Aseptic Double Seat Valve - An aseptic double seat valve has a housing, which has connections for two pipe conduits. A first valve seat and a second valve seat are arranged spaced apart from one another in the direction of a longitudinal axis in the housing between the connections for the two pipe conduits. A first closing body interacts in a sealing manner with the first valve seat, and a second closing body interacts in a sealing manner with the second valve seat. A first elongate valve stem, which is of hollow design is connected to the first closing body, and a second elongate valve stem, which extends through the interior of the first valve stem, is connected to the second closing body. A diaphragm, which has a radially inner opening, serves to seal off a gap present between the first valve stem and the second valve stem. An outer rim of the diaphragm is fixed in a sealing manner on the second closing body, and the inner rim of the diaphragm is fixed in a sealing manner on the first valve stem. | 11-06-2014 |
| 20150096634 | FLUID RECEIVER - An apparatus and system are disclosed for a fuel receiver. The apparatus includes a base having an inlet and an outlet that defines an interior channel through which fluid is flowable. The apparatus also includes a first valve movable relative to the base between a closed position and an open position allowing fluid flow through the inlet. The apparatus also includes a second valve independently movable relative to the base and the first valve, the second valve movable between a closed position and an open position allowing fluid flow through the inlet. The system includes the apparatus, and a fluid reservoir or tank in fluid communication with the apparatus. | 04-09-2015 |
