  • Patent number: 11059585
    Abstract: An aircraft store ejector systems and subsystems thereof. Embodiments can include a two-reservoir re-pressurization system wherein a remote reservoir is used to maintain desired pressure in a local ejector reservoir. The system can include a release valve having a vent valve and valve piston. The release valve can control release of pressurized gas to a pitch control valve. The pitch control valve can be configured to distribute the pressurized gas between two or more ejector piston assemblies. One or more of the ejector piston assemblies can include multiple concentric piston stages and piston chambers, the piston chambers configured to contain a volume of gas. The ejector piston assemblies can be configured to compress the volume of gas within the piston chambers as the piston stages are extended out from the aircraft. Such compression can provide a return force to the piston stages.

  • Patent number: 10612689
    Abstract: A manifold for water dispensing units includes a manifold body having: one or more inlet paths, an outlet path, a collecting chamber delimited by a lateral wall and communicating with the inlet paths and with the outlet path. The collecting chamber is configured to receive a cartridge body for the regulation of flow. A safety group is associated to the manifold body and includes: a flange removably attached to the manifold body, a safety shutter provided with through inlet gaps and with shut-off surfaces and a control body for the movement of the safety shutter: from a first position in which the through inlet gaps communicate with the inlet paths and contrast means prevent the separation of the control body and the cartridge body from the manifold body, to a second position in which the shut-off surfaces sealingly close the inlet paths. A sliding surface allows the separation of the control body and the cartridge body from the manifold body, and vice versa.

  • Patent number: 10449351
    Abstract: A drug administration valve (100) comprises a valve housing (200) having a plurality of drug inlets (D1 to D4) for receiving drug fluids, such as cytostatic, one flushing inlet (F) for receiving a flushing fluid, and an outlet (O). A valve member (300) rotationally arranged in the housing has a passageway (320; 321) presenting a single inlet (322) and a single outlet (324). The valve member (300) presents a plurality of drug positions for guiding an associated drug fluid to the outlet (O), and one or more flushing positions for guiding a flushing fluid through the same passageway (320; 321) as the drug fluids in order to flush said passageway (320; 321) from any drug residuals. The valve member (300) is prevented from rotating from one drug position to another drug position without passing one of said flushing positions.

  • Patent number: 9074691
    Abstract: A fluid flow control adjuster device controls fluid flow ratios when placed in-line with a tube that runs from a toilet fill valve to the overflow tube of a flush valve. The device comprises an adjuster having an adjuster body with an inlet and an outlet. The body includes an adjuster knob and a receiver gap, which is a gap between a body rotation stop and another edge at a top surface of the adjuster knob. A key is also provided which can be inserted between the body rotation stop and the edge of the adjuster so that the installer can dial in the correct percentage of fill. The key is a hub-like planar structure that matches the curvature of the receiver and includes a plurality of key fingers with each finger including indicia that correlate to settings for selecting a proper toilet bowl refill range.

  • Publication number: 20130220445
    Abstract: In a plug valve with a plug supported around its axis of rotation in a flow passageway of the valve housing, the plug is supported in a floating manner against a spring force pressing the plug against an annular sealing element. The spring force is provided by a spring element bearing against the valve housing and engaging with a trunnion of the plug. The sealing element is supported in a fixed position against a flow passage opening.

  • Patent number: 8286940
    Abstract: The present invention is directed to an injection molding valve configured to prevent the leaking or stringing of injected thermoplastic from the valve. The valve includes a housing having a first bore along a length thereof and a second bore intersecting the first bore. A rotatable member is inserted through the second bore and is in communication with a lever for the actuation thereof. The rotatable member includes a hole therethrough such that when the hole is aligned with the first bore, thermoplastic may travel freely through the first bore. The second bore further includes at least one groove in communication with a port for receiving injected thermoplastic. The injected thermoplastic is hardened to form an seal therein and configured to prevent thermoplastic from leaking out of the valve housing.

  • Patent number: 7703205
    Abstract: A high-pressure plug valve is refurbished by replacing a valve plug, a valve plug cage, and flow path inserts that line a flow path through the plug valve. The valve plug cage has first and second opposed flat side surfaces, each side surface has a port for receiving one of the replaceable flow-path inserts in a fluid-tight seal. In one embodiment, refurbishing the plug valve includes replacing at least one inset seal for sealing at least one of the ports when the plug is in a closed position to inhibit leakage through the valve at low fluid pressures.

  • Patent number: 6186164
    Abstract: A rotary valve includes a housing having a housing bore which can be laterally closed by bearing covers. Inside the housing, a cellular wheel is rotatably supported. A guiding device extends in an axial direction of the cellular wheel and serves for drawing the cellular wheel in the direction of its axis of rotation out of the housing bore. This guiding device includes an additional bearing which can be displaceable in the axial direction relative to that bearing cover which is on the guiding side. The additional bearing serves to support the cellular wheel temporarily during removal from the housing bore. This additional bearing can be connected to that end of a cellular wheel shaft which is situated at the side of the guiding device.
