Patent number: 9976683Abstract: A fluid connector having a longitudinal axis and selective open and closed conditions, includes an elongate conduit member extending along the longitudinal axis, an annular collar disposed about and having axial movement relative to the conduit member between the connector open and closed conditions, and a plurality of split nut members circumferentially distributed about the conduit member and having axial movement relative to the collar between the connector open and closed conditions. The plurality of split nut members and the collar are jointly rotatably about the longitudinal axis, and each split nut member has a distal end defining a threaded nut segment. The split nut member distal ends in the connector closed condition are constrained by the collar against radially separating movement relative to the longitudinal axis and cooperatively define a nut configured to threadedly engage a mating fluid fitting.Type: GrantFiled: March 20, 2015Date of Patent: May 22, 2018Assignee: MARSHALL EXCELSIOR COMPANYInventors: Frederick W. Blanchard, James C. Zuck

Patent number: 9874293Abstract: A fluid transfer system includes a transfer device coupled to a dry break coupler. The transfer device includes a valve assembly moveable between an open and a closed position. The valve assembly includes a main valve and a pilot valve. An actuator controls both the main valve and the pilot valve. A cam plate interconnects the actuator and the valve assembly. The cam plate provides a quick acting shutoff to quickly move the valve assembly to the closed position. A pivotal and rotatable connector couples the transfer device to the dry break coupler. A lock is integrated with the actuator to lock the valve assembly in the closed position.Type: GrantFiled: February 26, 2016Date of Patent: January 23, 2018Assignee: MARSHALL EXCELSIOR COMPANYInventors: Frederick W.

Patent number: 9581249Abstract: A valve assembly includes a housing having a first chamber, a second chamber, and a valve seat disposed therebetween. A valve head disposed in the housing and is moveable between an open position and a closed position. The valve head defines a bore extending along an axis from the first chamber to the second chamber when the valve head is in the closed position. A valve stem is disposed in the bore and is coupled to the valve head in the bore for moving the valve head between the open and closed positions. The valve assembly allows for selective fluid communication between the first and second chambers to alleviate pressure differences between the first and second chambers. In one embodiment, the valve stem moves in the bore between a sealed position and an unsealed position. In another embodiment, a check valve is disposed in the bore.Type: GrantFiled: November 20, 2013Date of Patent: February 28, 2017Assignee: MARSHALL EXCELSIOR COMPANYInventors: James C. Zuck, Alex L.

Patent number: 9310003Abstract: A fluid transfer system includes a transfer device coupled to a dry break coupler. The transfer device includes a valve assembly moveable between an open and a closed position. The valve assembly includes a main valve moveable between a closed-main valve position and an open-main valve position in response to movement of an actuator and a pilot valve moveable between a closed-pilot valve position and an open-pilot valve position in response to movement of the actuator. A configuration of the coupler and the transfer device is coupled together, the coupler valve being in the closed-coupler valve position and the main valve being in the closed-main valve position. A space between a face of the main valve and a face of the coupler valve is minimized to reduce fluid emissions upon uncoupling the transfer device from the coupler.Type: GrantFiled: May 15, 2014Date of Patent: April 12, 2016Assignee: MARSHALL EXCELSIOR COMPANYInventors: Frederick W.
