摘要： A valve assembly is disclosed for allowing fluid flow in a first direction and preventing fluid flow in a second direction. The valve assembly includes a housing for enclosing a substantially circular regulator assembly which extends diametrically across the housing. The regulator assembly comprises a hub portion which is positioned centrally within the housing and connecting members which extend radially toward a rim portion which is supported by the housing. The hub portion supports a disk-shaped substantially inflexible portion of the regulator assembly which extends over the connecting members to engage the rim portion and thereby prevent fluid flow in the second direction. The connecting members of the regulator assembly are adapted to flex and allow the disk portion to move off of the rim and thereby allow fluid flow through the valve in the first direction.

摘要： A dual valve assembly for use with a dispensing apparatus including a pump and a plurality of fluid containers. The valve assembly includes a housing containing an elastomeric regulator wherein the regulator includes a diaphragm portion for controlling fluid flow through the housing, and a vent valve structure for opening and closing air passages to supply air to the containers. The diaphragm portion includes an orifice, and the diaphragm portion is movable into and out of contact with a seat defined on the housing to control fluid flow from the containers and through the orifice during actuation of the pump. In addition, the vent valve structure includes a pair of vent membranes which open vent openings to the containers in response to negative pressure applied from the pump.

The hub portion supports a disk-shaped substantially inflexible portion of the regulator assembly which extends over the connecting members to engage the rim portion and thereby prevent fluid flow in a reverse flow direction through the regulator assembly. The connecting members of the regulator assembly are adapted to flex and allow the disk portion to move off of the rim and thereby allow fluid flow through the valve in the first direction.

摘要： The present invention provides a medical coupling site which is adapted to be attached directly to a standard male luer lock fitting. The coupling site includes a valve element contained within a tubular retainer. The retainer is provided with outwardly extending lugs for engaging the threaded locking collar of a male luer lock whereby the male luer lock will be held in positive mechanical locking engagement with the coupling site. The valve element is provided with rib members extending inwardly from an inner wall of the valve element toward a slit formed in a diaphragm such that the rib members act to bias the slit to a closed position. In addition, the valve element is formed with biasing means for engaging an inner wall of the retainer whereby the slit is further biased to a closed position.

摘要： The present invention provides a medical coupling site which is adapted to be attached directly to a standard male luer lock fitting. The coupling site includes a valve element contained within a tubular retainer. The valve element is formed of a resilient material having greater than that of the retainer, and has a diaphragm including a concave surface with a slit extending diametrically across the surface. The valve element is provided also with biasing means extending inwardly from an inner wall of the valve element into a passage in the valve element such that the biasing means act to bias the slit to a closed position. In a preferred form, the retainer has an outer wall with a maximum outer diameter of approximately 7 mm and an inner wall of the valve element has a minimum inner diameter of approximately 4 mm.

摘要： A non-stick treated valve including a pair of cooperating elastomeric surfaces positioned to engage each other to control fluid flow through the valve. A non-stick coating is applied to the cooperating surfaces to facilitate separation of the surfaces from each other during opening of the valve. The non-stick coating is in the form of an oily substance such as a fluid lubricant for forming a fluid film coating on the cooperating surfaces. In addition, the coating material is formed of a material which is dissimilar from the material forming the cooperating surfaces.

摘要： A fuel filler pipe seal includes upper and lower portions and a sealing lip positioned at the juncture of the upper and lower portions to engage an outer surface of a fuel nozzle and prevent the escape into the atmosphere of fuel fumes during a fueling operation. The lip lies in a plane which intersects a groove formed in an outer surface of the seal to receive a seat formed on a mounting bracket mounted in an upper end of the filler pipe, and the upper portion of the seal has an umbrella valve formed integrally with it which covers a vent opening in the bracket and is preloaded to release at a predetermined pressure. By positioning the sealing lip adjacent the seat-receiving groove a better seal with a fuel nozzle is formed, premature release of the umbrella valve is avoided, and damage to the seal when the nozzle is thrust into the filler pipe is minimized.

摘要： A needle valve is formed by molding a resilient tip to a rigid body having a tip receiving cylindrical portion or barrel which includes tip retaining means for securing the resilient tip thereto. The tip is then ground until the outer edge of the barrel is engaged to form a resilient single angle or simple conical tip to thereby eliminate distortions which may be present in the molded tip. The tip retaining means comprises either a socket formed into the distal end of the barrel or a mushroom-shaped bayonet projection extending therefrom.
