Abstract: A valve assembly includes a receptor valve assembly and an insert valve assembly each defining a normally closed fluid passage. The insert and receptor valve assemblies each include a valve activation structure engageable with one another and having corresponding helical grooves and splines for opening the receptor and insert valve assemblies upon engagement of the valve activation structures and rotation of the insert valve assembly relative to the receptor valve assembly wherein their respective fluid passages are interconnected. The insert and receptor valve assemblies are configured to provide substantially no fluid passage therebetween when closed, thereby providing little or no spillage of fluid when disconnecting the insert and receptor valve assemblies.

Abstract: A dispensing valve includes a body defining a passage with a first opening and a second opening. The body further has an outer surface with a lock surface and an open surface. A pluger is slidably disposed within the passage for movement between a first position wherein a fluid tight seal is formed between the plunger and the body for preventing fluid flow between the first opening and the second opening, and a second position wherein fluid flow is permitted between the first opening and the second opening. An arm extends from the plunger and includes a projection slidably engageable with the outer surface of the body. The arm includes biasing structure for biasing the projection against the outer surface of the body. The projection is engageable with the lock surface when the plunger is in the first position for maintaining the plunger in the first position.

Abstract: An improved self-tightening fitting and fitting connector for use with soft tubing includes a stem having a flange at one end over which a piece of soft tubing may be pulled, and a sleeve which is slidable over the stem and has an inwardly extending lip with a connect surface thereon.

Abstract: A shutoff valve (26) including a plunger (28) slidably mounted in a housing (30). The plunger (28) being slidable between an open and a closed position. The plunger (28) having a front end and a back end and defining a path flow of fluid therethrough. A back end (32) of the plunger (28) having inclined surfaces (50). Projections (34) extend from the back end (32) of the housing (30) and cooperate with the inclined surfaces (50) to bias the plunger (20) into the closed position.

Abstract: An improved self-tightening fitting and fitting connector for use with soft tubing includes a stem having a flange at one end over which a piece of soft tubing may be pulled, and a sleeve which is slidable over the stem and has an inwardly extending lip with a contact surface thereon. A releasable ratchet mechanism prevents movement of the sleeve away from the flange, so that tubing can be secured tightly between the contact surface of the sleeve and the flange. When tension is applied to the tubing, the lip portion catches on the tubing, urging the contact surface tighter against the flange, preventing the tubing from creeping through the clamping couple formed by the sleeve and flange. When it is desired to disconnect the tubing, the ratchet mechanism can be released. The method of use is also disclosed.
