Abstract:
An aerosol delivery device (100) having a check valve therein for use with refilling the aerosol delivery device is provided. The aerosol delivery device may comprise at least one housing (104) defining a refillable reservoir for storing an aerosol precursor composition, and a heating element (110) contained within the at least one housing and configured to activate and vaporize components of the aerosol precursor composition. A connector (124) may be coupled to the at least one housing and sealably connectable with a container of aerosol precursor composition for refilling the reservoir. The connector may include a check valve configured to enable only a one-way flow of aerosol precursor composition from the container into the reservoir when the connector is sealably connected with the container.
Abstract:
Provided is an integrated check-relief valve in which a retreat amount of a valve seat member can be regulated when a relief valve is in operation, and an inclination of the valve seat member and a slant of a relief spring can be prevented. In an integrated check-relief valve 1 including a valve housing 2, inside the valve housing 2, a check ball 3 and a valve disk 4 with which the check ball 3 can come into contact are provided so as to be movable in an axial direction, a check spring 5 which urges the check ball 3 to the valve disk 4 side, a relief spring 6 which urges the valve disk 4 to the check ball 3 side, and a guide member 8 which guides the relief spring 6 from an inner circumference side are provided. A movement amount of the valve disk 4 with respect to a side where the relief spring 6 contracts is regulated by a distal end portion of the guide member 8.
Abstract:
The invention relates to a valve (10), in particular a hydraulic valve (10) of a device carrying a fluid. Said valve comprises a valve bushing (12) having a passage (14), formed in the longitudinal direction (L) between an inlet opening (32) and an outlet opening (30), and a particulate filter (20), which is arranged on the inlet opening (32) of the passage (14). The outer edge (22) of said particulate filter (20) is connected in a fluid-tight fashion to a collar (34) arranged at an inlet opening (32) of the passage (14).
Abstract:
Die Vorrichtung zur Begrenzung der Zufuhr von Kraftstoff aus einer Hochdruckversorgung über einen steuerbaren Injektor in den Brennraum einer Brennkraftmaschine umfasst ein Gehäuse mit einem druckversorgungsseitigen Gehäuseeinlass und einen injektorseitigen Gehäuseauslass, die über wenigstens einen eine Drossel aufweisenden Kanal miteinander hydraulisch verbunden sind, und ein in einer Kammer zwischen einer Ausgangsstellung und einer Endstellung längsverschiebbares und entgegen der Strömungsrichtung federvorgespanntes Schließglied, das eine Strömungsverbindung zwischen dem Gehäuseeinlass und dem Gehäuseauslass steuert, wobei der wenigstens eine Kanal radial außerhalb der Kammer verläuft.
Abstract:
Die Erfindung betrifft ein Rückschlagventil mit einem Ventilgehäuse und einem in dem Ventilgehäuse beweglich gelagerten, über ein Federelement (16) belasteten Ventilkörper (14) und ist dadurch gekennzeichnet, dass das Ventilgehäuse außenseitig mit einem Zapfen (18) versehen ist, der Mittel zur Fixierung des Zapfens (18) in einer Öffnung eines Bauteils aufweist.
Abstract:
The invention is related to an apparatus comprising a valve body comprising at least two inlet channels (302; 304) and at least one outlet channel (306) and forming a central cavity (308) connecting the at least two inlet channels (302; 304) and the at least one outlet channel (306), wherein the central cavity (308) encloses a blocking assembly (310; 312; 314; 322; 330; 332; 334; 336) arranged for closing each of the at least two inlet channels (302; 304) by default and for opening an inlet channel (302; 304) when fluid pressure is applied from that inlet channel (302; 304); wherein each of the at least two inlet channels (302; 304) is configured for fluid communication with a respective reservoir of at least two reservoirs. The invention is further related to a medical device for delivering at least two drug agents from at least two separate reservoirs comprising an apparatus of the aforementioned kind.
Abstract:
A cushion with a support pad comprising a plurality of compressible suspension elements with a cover top and bottom joined together to form an impervious barrier, and a valve in fluid communication with the plurality of compressible suspension elements that allows the controlled expulsion of air until a user positioned on the cushion is optimally immersed in the cushion. When the user is removed from the cushion, the valve allows ingress of air into the cushion. In one aspect, the valve comprises an expansion valve controls air flow out of and into the cushion. In one aspect, the valve comprises a labyrinth seal that dampens air flow and pressure spikes. The valve comprises a pressure responsive compression spring that controls the expulsion of air from the cushion and, consequently, adjusting the immersion depth of the seated user.
Abstract:
A cooler bypass valve apparatus installed the apparatus between a heat exchanger and conduits coupled to a device carrying fluid that needs to be cooled. A housing includes an inlet port and first and second outlet ports. At least one thermal actuator and at least one valve are mounted in a fluid flow passageway in the housing and operative in response to the fluid temperature to move the at least one valve between operative positions opening and closing fluid flow from the inlet port through the first and second outlet ports between a heat exchanger bypass loop and a heat exchanger cooling loop. In another aspect, two thermal actuators control a separate valve associated with the first and second outlets between open and closed positions enabling fluid flow from the inlet port exclusively through one of the first and second outlet ports or in a combined partial flow through both of the first and second outlet ports.
