## Abstract

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.

## Claims

### Claim 1

A fluid transfer device for coupling to a threaded receiver, said fluid transfer device comprising:
a housing defining a longitudinal axis and a first race;
an actuator having a grasping portion moveable relative to said housing;
a valve assembly disposed in said housing and operatively coupled to said actuator;
a connector pivotally and rotatably coupled to said housing and being threaded to engage a threaded receiver, said connector defining a second race; and
a plurality of bearing members disposed in said first race and said second race for allowing rotational movement of said connector relative to said housing about said longitudinal axis,
wherein said first and second races are configured to enable pivoting of said connector between different angular positions relative to said longitudinal axis to ease coupling of said fluid transfer device to the threaded receiver.

### Claim 2 (depends on 1)

A fluid transfer device as set forth in claim 1 wherein said first race has a first width and said second race has a second width, said first width being greater than said second width.

### Claim 3 (depends on 1)

A fluid transfer device as set forth in claim 1 wherein said first race has a first cross-sectional shape with a first radius portion, a second radius portion, and a flat middle portion connecting said first radius portion and said second radius portion.

### Claim 4 (depends on 3)

A fluid transfer device as set forth in claim 3 wherein said middle portion has a length of from 0.01 inches to 0.1 inches.

### Claim 5 (depends on 3)

A fluid transfer device as set forth in claim 3 wherein said second race has a second cross-sectional shape with a semi-circular portion.

### Claim 6 (depends on 5)

A fluid transfer device as set forth claim 5 wherein said semi-circular portion matches a shape of said bearing members.

### Claim 7 (depends on 6)

A fluid transfer device as set forth in claim 6 wherein said bearing members are ball bearings.

### Claim 8 (depends on 1)

A fluid transfer device as set forth in claim 1 wherein said housing includes an adapter with said connector being pivotally and rotatably coupled to said adapter.

### Claim 9 (depends on 8)

A fluid transfer device as set forth in claim 8 wherein said connector includes a coupling element and a collar fixed to said coupling element, said collar being threaded.

### Claim 10 (depends on 9)

A fluid transfer device as set forth in claim 9 wherein said coupling element is pivotally and rotatably coupled to said adapter.

### Claim 11 (depends on 9)

A fluid transfer device as set forth in claim 9 wherein said adapter includes said first race and said coupling element includes said second race.

### Claim 12

A fluid transfer device for coupling to a threaded receiver, said fluid transfer device comprising:
a housing defining a longitudinal axis and a first race having a first cross-sectional shape with a first radius portion, a second radius portion, and a flat middle portion connecting said first radius portion and said second radius portion;
an actuator having a grasping portion moveable relative to said housing;
a valve assembly disposed in said housing and operatively coupled to said actuator, said valve assembly including a main valve moveable between an open-main valve position and a closed-main valve position in response to movement of said actuator and a pilot valve moveable between an open-pilot valve position and a closed-pilot valve position in response to movement of said actuator;
a connector pivotally and rotatably coupled to said housing and being threaded to engage a threaded receiver, said connector defining a second race having a second cross-sectional shape with a semi-circular portion; and
a plurality of ball bearings disposed in said first race and said second race for allowing rotational movement of said connector relative to said housing about said longitudinal axis,
wherein said first and second races are configured to enable pivoting of said connector between different angular positions relative to said longitudinal axis to ease coupling of said fluid transfer device to the threaded receiver.

### Claim 13 (depends on 12)

A fluid transfer device as set forth in claim 12 wherein said first race has a first width and said second race has a second width, said first width being greater than said second width.

### Claim 14 (depends on 12)

A fluid transfer device as set forth in claim 12 wherein said middle portion has a length of from 0.01 inches to 0.1 inches.

### Claim 15 (depends on 12)

A fluid transfer device as set forth in claim 12 wherein said semicircular portion matches a shape of said ball bearings.
