## 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 system comprising:
a coupler defining a coupler inlet and a coupler outlet and a coupler valve disposed therein and being moveable between an open-coupler valve position and a closed-coupler valve position;
a transfer device defining an inlet and an outlet, an actuator having a grasping portion moveable fore and aft, said actuator moveable between a first position and a second position, and a valve assembly disposed therein and operatively coupled to said actuator, said valve assembly including a main valve moveable between a closed-main valve position and an open-main valve position in response to movement of said actuator and a pilot valve moveable between a closed-pilot valve position and an open-pilot valve position in response to movement of said actuator wherein said main valve is in said closed-main valve position and said pilot valve is in said closed-pilot valve position when said actuator is in said first position; and
wherein a configuration of said coupler and said transfer device being coupled together, said coupler valve being in said closed-coupler valve position and said main valve being in said closed-main valve position, a space between a face of said main valve and a face of said coupler valve is minimized to reduce fluid emissions upon uncoupling said transfer device from said coupler.

### Claim 2 (depends on 1)

A fluid transfer system as set forth in claim 1 wherein said minimized space is achieved due to a proximity of said main valve to said outlet and a proximity of said coupler valve to said coupler inlet.

### Claim 3 (depends on 1)

A fluid transfer system as set forth in claim 1 wherein said coupler valve includes a valve face of a circular shape.

### Claim 4 (depends on 1)

A fluid transfer system as set forth in claim 1 wherein said main valve includes a valve face of a circular shape.

### Claim 5 (depends on 1)

A fluid transfer system as set forth in claim 1 wherein said coupler includes a coupler spring continuously biasing said coupler valve in said closed-coupler valve position.

### Claim 6 (depends on 1)

A fluid transfer system as set forth in claim 1 wherein said coupler valve includes a guide rod and a guide mount fixed to said coupler and slidably receiving said guide rod as said coupler valve moves between said open-coupler valve position and said closed-coupler valve position.

### Claim 7 (depends on 1)

A fluid transfer system as set forth in claim 1 wherein said coupler includes a coupler seal on said coupler valve to prevent fluid from leaking out of said coupler when said coupler valve is in said closed-coupler valve position.

### Claim 8 (depends on 1)

A fluid transfer system as set forth in claim 1 wherein said transfer device includes a rotatable connector for connection to said coupler.

### Claim 9 (depends on 8)
