  • Publication number: 20210048113
    Abstract: A check valve may include a valve body forming a central passage extending from a first side of the valve body to a second side of the valve body. A valve pin may be located within the central passage, where the valve pin includes a sealing head that selectively contacts a valve seat of the valve body to control flow of a fluid through the central passage. A spring may be included, where the spring has a first end that is fixed relative to the valve pin and a second end fixed to a spring seat. The valve body and the spring seat may be fixed to one another without the use of threads.

  • Patent number: 9328836
    Abstract: A pressure regulator valve has a housing that defines a fluid passage and a flat seat disposed around an opening of the fluid passage and exit ports. A pin with a raised conforming elastomeric embossment that contacts the seat when the valve is closed is axially disposed in the housing. The pin is biased to maintain the elastomeric embossment in contact with the seat to maintain the valve closed and control an opening pressure of the valve. Flow of fluid through and out of the pressure regulator valve housing is controlled through adjustment of a level of this biasing. The fluid flows across the flat seat and between the flat seat and the embossment when the valve is open in such a manner that the flow is generally laminar and such that the valve minimizes pressure gain at the onset of flow.

  • Patent number: 8814456
    Abstract: A device employed by a user for applying a self-adhesive product to a surface may include an outer housing configured for gripping by a single hand of the user, the outer housing having a distal end, and a volume of self-adhesive product disposed within the outer housing. An automatic dispensing mechanism is disposed within the outer housing and operatively coupled to the outer housing and the volume of self-adhesive product, the automatic dispensing mechanism configured to advance at least a portion of the volume of self-adhesive product through the outer housing distal end in response to a manual actuation force applied to the outer housing.

  • Patent number: 7114344
    Abstract: An air conditioner service fitting is provided and includes a valve body comprising a threaded bore and an annular valve seat extending around the bore. The valve body is configured and the valve seat is positioned such that all fluid that passes through the bore crosses the valve seat. A twist-to-open valve is disposed in the bore and threadedly engages with the valve body. The twist-to-open valve includes a valve element configured to form a polymer-to-metal seal with the valve seat. The polymer-to-metal seal stops substantially all fluid flow through the bore and the flow path when the twist-to-open valve is closed. The valve body further includes an external connection feature disposed around the bore. The valve body comprises an external sealing surface.

  • Patent number: 6708716
    Abstract: A valve assembly includes a valve body having a passageway and first and second oppositely facing valve seats that extend around the passageway. First and second valve elements are positioned in the passageway to seal against the respective valve seats, and a spring biases the first valve element to the closed position against the first valve seat. The valve seats are spaced sufficiently closely together along the passageway that the first valve element, when positioned against the first valve seat, holds the second valve element away from the second valve seat. For this reason, the spring also biases the second valve element away from the second valve seat.

  • Publication number: 20030217770
    Abstract: A combination thermal and pressure relief valve is disclosed that includes a first housing having an opening at a first end and a pathway extending towards the opening from a second end of the first housing. A second housing is partially received in the opening of the first housing, and the first and the second housings define a chamber adjacent the pathway. An exitway extends from the chamber to an exterior of the valve. A bearing element is within the chamber adjacent the pathway and is larger than a width of the pathway. A spring is within the chamber, is under compression, and in line with the bearing element. A thermal element is also within the chamber and in line with the spring. The thermal element melts at a predetermined temperature. The spring exerts a force on the bearing element such that the bearing element is biased against the pathway and forms a seal between the chamber and the pathway.

  • Patent number: 6401693
    Abstract: A fuel injection system for an internal combustion engine includes a pressure spike attenuator that is installed between the pump and fuel rail inlet of the system. This pressure spike attenuator includes an expandable pressure vessel having a sidewall that is corrugated in cross-section to facilitate volumetric expansion of the pressure vessel. A solenoid valve includes a tapered needle that is moved between an opened and a closed position. In the opened position, the fuel pump, the pressure vessel, and the fuel rail are all in fluid communication with one another. In the closed position, the pressure vessel is isolated from both the fuel pump and the fuel rail, and the fuel rail is isolated from both the fuel pump and the pressure vessel.

  • Patent number: 6273397
    Abstract: An air conditioner access fitting includes a valve body having a threaded bore and an annular valve seat extending around the bore. A twist-to-open valve is disposed in the bore and threadedly engaged with the valve body. The valve includes a valve element configured to form a metal-to-metal seal with the valve seat. A valve core is disposed in a second bore formed in the twist-to-open valve, and the valve core operates selectively to open and close a flow path extending through the second bore. The valve body further includes a quick connect shoulder disposed around the bore. An associated service fitting includes a quick release mechanism, a wrench for rotating the twist-to-open valve, and a valve core depressor for opening the valve core.
