摘要： A catheter check valve assembly has a body member with a wall defining a generally cylindrical chamber and a transverse wall having an aperture lying on the axis of such chamber. A duckbill valve and an end cap supporting a catheter are positioned on one side of the transverse wall. A separator has a major portion positioned in said cylindrical chamber and an elongated cylindrical probe extending from said major portion. The separator is axially moveable from a retracted position where the probe is out of contact with the duckbill valve to a forward position extending through and opening the duckbill valve. A trocar may be extended through the catheter check valve assembly when the separator is in the forward position.

摘要： A fueling nozzle for pressurized fuel systems having a body connectable to a tank inlet. The body includes an axially displaceable valve movable between a closed retracted position and an extended open position. Connection of the body to the tank inlet occurs upon rotation of the connection sleeve and positioning of the valve is achieved by a rotatable cam sleeve having a cam slot in which a valve-mounted follower is located. An interlock senses mounting of the body on the tank inlet permitting rotation of the connection sleeve in a locking direction and upon the connection sleeve being fully rotated to a locked condition a second interlock permits rotation of the cam sleeve and valve movement from the closed to the open position. The nozzle is characterized by reduced flow resistance characteristics and safe operation.

摘要： A frangible fluid fitting of the crash-worthy type utilizing a detent holding a self-closing valve in the open position. The detent engages a plurality of balls confined in a recess circumscribing the fitting attachment surface whereby only partial fracture of the fitting in any direction causes the self-sealing valve to close. One embodiment of the fitting permits both gravity and pressurized tank filling with automatic valve closing when the tank is full during pressurized filling.

摘要： The invention pertains to an oil drain fitting for internal combustion engines which permits a quick draining of the oil. A body threaded into the conventional oil pan drain hole includes an axial passage having a tubular valve reciprocally mounted therein. The valve is open at its lower end and closed at its inner end having a head which seats against the inner end of the body. The lower end of the valve includes an abutment surface for engagement by a drain conduit fitting for axially displacing the valve inwardly to open the valve and permit flow therethrough. A cap may be mounted on the body to enclose the lower end of the valve when the fitting is not in use.

摘要： A self-contained tank filling fitting having dual operation wherein the fitting may be used with a gravity fluid supply system or a pressurized fluid supply system. The fitting includes an elbow having an upper end closed by a removable cap, and a pressurized filling port located in the bend of the elbow aligns with a tank port to reduce resistance to pressurized fluid filling. An automatic differential pressure valve controlled by a float operated vent automatically closes the pressurized filling port upon the tank being filled.

摘要： An annular fluid seal for pressurized fluid systems particularly for use with a coupling having interconnectable self-sealing male and female parts. The two-part seal is mounted within an annular gland recess within the male part and includes a relatively rigid primary annular body of synthetic plastic material having an interference fit with the male coupling part poppet valve. The outer diameter of the seal body includes an annular recess receiving an elastomeric O-ring, and the mass of the primary seal body provides maximum strength within the confines of the gland recess to resist deformation due to pressurized fluid to prevent blowout of the seal from its recess.

摘要： The invention pertains to a valve particularly suitable for sampling internal combustion engine lubricating oil while under pressure being used within the engine and consists of a valve body placed within a pressurized oil conduit. The body includes an orifice having a valve movable between open and closed positions by a sample collecting receptacle wherein one hand operation is readily achieved. The valve includes a proboscis suitable for piercing the sample receptacle diaphragm, and a spring produces a positive biasing force on the valve toward the closed position. A pressure balancing piston connected to the valve balances the force necessary for valve operation due to internal pressure. A removable cover protects the valve and proboscis when not in use.
