Abstract
Abstract A refueling nozzle having a slidably mounted valve sleeve engageable with a valve seat carried by a rod adjacent a protruding nose. The valve seat being slidable on the rod so that the valve seat and sleeve may be moved, while maintaining a sealing relationship with each other, to take up the gap between the locking elements and the sleeve. Further, the rod is supported remote from the nose for limited movement in all angular directions to compensate for misalignment of the nose with a companion part of an associated drogue. The valve sleeve is slidably mounted in the nozzle body by a bearing member which also serves to retain in place latch elements for retaining the valve sleeve in a latched sealing engagement with the valve seat.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
101 words
In a dispensing head of the type including a nose, a valve seat associated with said nose, and a valve sleeve resiliently urged towards engagement with said valve seat for sealing against flow and relatively movable to an open position to permit flow around said valve seat and said nose, the improvement comprising mounting means mounting said valve seat for limited axial movement relative to said nose, and means resiliently urging said valve seat away from said nose towards said valve sleeve for maintaining the sealing engagement between said valve sleeve and said valve seat when said sleeve is accidentally bumped.
Claim 2
Dependent Claim
101 words
In a dispensing head of the type including a nose, a valve seat associated with said nose, and a valve sleeve resiliently urged towards engagement with said valve seat for sealing against flow and relatively movable to an open position to permit flow around said valve seat and said nose, the improvement comprising mounting means mounting said valve seat for limited axial movement relative to said nose, and means resiliently urging said valve seat away from said nose towards said valve sleeve for maintaining the sealing engagement between said valve sleeve and said valve seat when said sleeve is accidentally bumped.
Claim 3
Dependent Claim
33 words
The dispensing head of claim 1 wherein said mounting means includes a rod having said nose mounted thereon in a relatively fixed position, and said valve seat being slidably mounted on said rod.
Claim 4
Dependent Claim
28 words
The dispensing head of claim 2 together with cooperating stop surfaces on said valve seat and said rod limiting movement of said valve seat away from said nose.
Claim 5
Dependent Claim
35 words
The dispensing head of claim 1 wherein the means resiliently urging said valve sleeve towards said valve seat is of a greater force than said means resiliently urgins said valve seat away from said nose.
Claim 6
Dependent Claim
44 words
The dispensing head of claim 1 wherein sealing means peripherally seal said valve seat relative to said nose, and vent means venting the space between said valve seat and said nose to assure freedom of return of said valve seat by said valve sleeve.
Claim 7
Dependent Claim
111 words
In a dispensing head of the type having a nose seatable in a valve member during the coupling of said dispensing head with a drogue and wherein said nose is carried by an elongated rod, the improvement comprising mounting means mounting said rod and the nose carried thereby for limited pivoting movement relative to its longitudinal axis permitting pivotal displacement of said nose to compensate for misalignment of said dispensing head and an associated valve member, said mounting means including a support having a spherical seat, a spherical surface carried by said rod for seating on said spherical seat, and retaining means retaining said spherical surface seated against said spherical seat.
Claim 8
Dependent Claim
111 words
In a dispensing head of the type having a nose seatable in a valve member during the coupling of said dispensing head with a drogue and wherein said nose is carried by an elongated rod, the improvement comprising mounting means mounting said rod and the nose carried thereby for limited pivoting movement relative to its longitudinal axis permitting pivotal displacement of said nose to compensate for misalignment of said dispensing head and an associated valve member, said mounting means including a support having a spherical seat, a spherical surface carried by said rod for seating on said spherical seat, and retaining means retaining said spherical surface seated against said spherical seat.
Claim 9
Dependent Claim
24 words
The dispensing head of claim 6 wherein said retaining means includes mating surfaces on said support and said rod remote from said spherical seat.
Claim 10
Dependent Claim
39 words
The dispensing head of claim 6 wherein said retaining means includes mating surfaces on said support and said rod remote from said spherical seat, and said spherical surface is axially adjustable relative to said mating surface on said rod.
Claim 11
Dependent Claim
81 words
In a dispensing head of the type including a body, a sleeve slidably mounted in said body, and latch elements carried by said body for locking said sleeve in a predetermined position, the improvement comprising single means forming bearing means for said sleeve and retaining said latch elements in said body, said means is in the form of a bearing sleeve between said body and said sleeve, and said bearing sleeve has retaining means thereon for retaining latch elements in place.
Claim 12
Dependent Claim
81 words
In a dispensing head of the type including a body, a sleeve slidably mounted in said body, and latch elements carried by said body for locking said sleeve in a predetermined position, the improvement comprising single means forming bearing means for said sleeve and retaining said latch elements in said body, said means is in the form of a bearing sleeve between said body and said sleeve, and said bearing sleeve has retaining means thereon for retaining latch elements in place.
Claim 13
Dependent Claim
42 words
The dispensing head of claim 9 wherein said bearing sleeve being in the form of a flat sheet shaped within said body and has at least one ear struck therefrom and interlocked with said body and preventing said bearing sleeve from moving.
Claim 14
Dependent Claim
97 words
In a dispensing head of the type including a body, a sleeve slidably mounted in said body, and latch elements carried by said body for locking said sleeve in a predetermined position, the improvement comprising single means forming bearing mEans for said sleeve and retaining said latch elements in said body, each latch element has trunnions projecting therefrom, said body has a socket receiving said trunnions, a one direction access opening into said socket, and said means being a retainer engaging each latch element and restraining the same against retraction of said trunnions from the respective socket.
Claim 15
Dependent Claim
97 words
In a dispensing head of the type including a body, a sleeve slidably mounted in said body, and latch elements carried by said body for locking said sleeve in a predetermined position, the improvement comprising single means forming bearing mEans for said sleeve and retaining said latch elements in said body, each latch element has trunnions projecting therefrom, said body has a socket receiving said trunnions, a one direction access opening into said socket, and said means being a retainer engaging each latch element and restraining the same against retraction of said trunnions from the respective socket.
Claim 16
Dependent Claim
30 words
The dispensing head of claim 11 wherein said means is in the form of a bearing sleeve between said body and said sleeve, and said sockets open towards said sleeve.
