A coupling manifold assembly has both regulated and unregulated flow orientations and includes a manifold body and a pressure regulator couplably received into the manifold body. The manifold body includes a pair of connection ports between which flow is movable through the manifold body, with the pressure regulator being received into a flow path between the connection ports. The pressure regulator is configured to regulate flow in a first direction between the connection ports and to allow for unregulated flow in an opposite second direction between the connection ports.

Pressure regulated coupling manifold assembly

A sensor including a buffer material layer configured to at least partially deflect when a force or pressure is imparted on the buffer material layer; and an electroactive polymer (EAP) cartridge in operative contact with the buffer material layer, wherein the EAP cartridge is configured to generate an output signal that corresponds to an amount of strain imparted on the EAP cartridge. The EAP cartridge may be used in a variety of sensing applications including as a pressure sensor integrated into a fluid connector. One aspect of the invention provides for selection of a buffer material layer based upon a desired pressure range.

Electroactive polymer based pressure sensor

A coupler that can be configured for easy insertion and removal from an unthreaded cavity within a manifold or other part. The coupler includes an axially movable lock member that also carries a valve member for sealing against a valve seat of a main coupler body. The coupler also has a plurality of radially flexible fingers spaced apart by slots, and a lock member has one or more stop portions that engage the fingers to prevent radial collapse of the fingers for retention of the coupler in the cavity in the part.

Snap-in-place valved coupler

Improvement in a quick disconnect coupling that includes a tubular coupler half, having a radially outwardly-directed roller on an outer surface portion thereof; a tubular nipple half, having a push-to-connect mechanism, including a cup-shaped member, concentrically surrounding a nipple body portion, this mechanism including a locking device having a basically L-shaped contoured slot including a helically-directed ramp inlet and a locking slot portion; the improvement comprising that the push-to-connect mechanism includes the rotatable journaling of the cup-shaped member, for limited rotational pivoting relative to the nipple half; this mechanism also including a biasing member for concurrently normally biasing the cup-shaped member to an at-rest position relative to the nipple body. A method for joining includes an initial contact between the axially-aligned roller and the helical ramp; further interaction rotationally displacing the cup shaped member until the roller enters the locking portion, resulting in reverse pivoting of the cup-shaped member.

Push-to-connect mechanism and method, for a coupling

A generally cylindrical quick disconnect female cryogenic coupler, interconnected with a cryogenic fluid transfer apparatus, includes a coupler body with a first cavity housing a laterally severed tubular bushing, an adaptor having one end attached to the coupler body and another end to the apparatus, a normally closed-biased valve between the coupler body and the adaptor, a coupling sleeve, attached to the coupler body having, a frusto-conical inlet portion, and a vent fitting having one end connected with a coupling sleeve radial aperture and another end in operative connection with a cryogenic fluid storage vessel, associated with the noted apparatus, to permit the inlet purging by using the vessel's own gaseous phase as a purging medium during liquid fluid transfer operation. The severed bushing inhibits ice formation, at an inlet/male nipple interface during the noted transfer. A method for purging moisture at the noted interface is also set forth.

Quick disconnect cryogenic coupler

A cryogenic coupling device includes a valved receptacle and a valved nozzle. Rollers in an outer collar of the receptacle are received in helical channels along a collar of the nozzle. A notch or detent in each of the channels provides a vent position to vent fluid before the nozzle is fully disconnected from the receptacle. Interface seals on the nozzle include first and second annular seals that function as ice and containment scrapers, as well as fluid seals. The nozzle has a rotatable handle assembly, isolated from the fluid path, which provides easy connect and disconnect of the nozzle from the receptacle. The handle assembly includes a thermal break, and is easily removable from the nozzle, along with other parts of the nozzle and receptacle, for service and maintenance.
