  • Patent number: 8640271
    Abstract: A cartridge unit for use with a urinal is disclosed that does not need water to work nor does it use a body of oily liquid sealant as an odor barrier. The odor trap cartridge unit used in this urinal has a spring locking mechanism that works as a valve. It is opened by liquid weight when the urinal is used and lets urine or any other liquid pass downwardly through it and prevents odors from flowing back up towards the room. The cartridge unit has a few disks, two main cylindrical devices, a spring, a fastener, an o-ring, and a coupling; these all operate to open and close a spring sealed trap. These are all placed within a unique three-sized shell that supports the entire cartridge and is fitted into a urinal opening. An umbrella shaped part completes the cartridge by protecting its components from violent fluid flow.

  • Patent number: 8561703
    Abstract: An apparatus usable with a well includes a gas lift valve having a check valve arrangement located between an annulus and a passageway of a tubing. The check valve arrangement is adapted to selectively allow fluid flow from the check valve arrangement from an inlet side of the check valve arrangement to an outlet side of the check valve arrangement, and is biased to prevent a leakage flow through the check valve arrangement from the outlet side to the inlet side. The check valve arrangement is defined by a valve element movable into and out of engagement with a valve seat wherein one of the valve element and the valve seat has a first sealing structure engageable with a second sealing structure on the other of the valve element and the valve seat. At least one of the first and second sealing surfaces include at least one pair of sealing members.

  • Patent number: 8544497
    Abstract: Fluid transfer apparatus including a body having a bore formed through at least a portion of its interior. Contained within the bore is a movable plunger that moves without changing the axial dimensions of the body. A first end of the body contains a face designed to be attached to an upstream component. A second end of the body is connected to a downstream component such as a filter, pipeline, etc. A first end of the plunger, when it is in the closed position, is in alignment with the face of the body, which combined form a steamable surface and a sterile barrier against the environment to the remainder of the interior of the body, the plunger and downstream components. An outer annular collar is rotatable relative to the body and causes the plunger to move axially within the bore from an open to a closed position.

  • Patent number: 8517051
    Abstract: A flow control valve includes a body portion including a first end, a second end and an axially extending passageway. A metering valve is included that is axially moveable under the influence of fluid pressure from a rest position to a flow restricting position. In the flow restricting position, the metering valve can restrict the flow of fluid through the axially extending passageway. The metering valve includes an upstream portion and a downstream portion. The upstream portion has a flattened top spherical shape. A biasing device is provided that normally biases the metering valve in the rest position, and for provides resistance to movement of the metering valve to the flow restricting position.

  • Patent number: 8356587
    Abstract: A positive crankcase ventilation valve assembly including a housing having a fluid inlet and outlet. A poppet valve is arranged in the housing between the fluid inlet and outlet and is movable in a axial direction between a plurality of positions. The positions respectively define a plurality of fluid flow rates. A plurality of ribs extend radially from either the poppet valve and the housing in an axial direction. The ribs define a bearing surface between the housing and the poppet valve. In this manner, the poppet valve is supported within the housing with a reduced bearing surface area while aligning the poppet valve relative to the housing throughout its movement between the positions. In another embodiment, the poppet valve is eliminated to prevent problems associated with an improperly operating poppet valve. A diaphragm is arranged in the housing between the fluid inlet and outlet.
