## Abstract

A volatile liquid refueling apparatus, which includes a probe, and a receiver including a dual locking mechanism whereby said apparatus can be locked in either an open position or a closed position, and a safety lock which disables or enables access to the dual locking mechanism when manually.

## Claims

### Claim 1

A volatile liquid refueling apparatus, comprising:
a probe;
a receiver including a dual locking mechanism whereby said apparatus can be locked in either an open position or a closed position, and a safety lock which disables or enables access to the dual locking mechanism when manually activated;
whereas said receiver includes a locking plunger assembly, having a plunger with a housing having a plunger slot;
whereas said safety lock unlocks and locks said locking plunger assembly;
whereas said safety lock comprises a lock ramp pin assembly which includes a lock ramp pin having a lock diameter area and a ramp area; and
said lock ramp pin has a ramp pin slot, and is configured such that when said plunger slot and said lock ramp pin slots are aligned, the safety lock is activated and depression of the plunger is prevented, and when said plunger slot and said lock ramp pin slots are not aligned, the safety lock is deactivated and depression of the plunger is allowed.

### Claim 2 (depends on 1)

The volatile liquid refueling apparatus of claim 1 wherein:
said lock ramp pin assembly includes lock dogs positioned in lock dogs bores, such that when said safety lock is activated, said lock dogs are constrained to contact said lock diameter area of said lock ramp pin and are prevented from release, which prevents depression of said plunger, and when said safety lock is deactivated, said lock dogs allowed to contact said ramp area of said lock ramp pin and are released, which allows depression of said plunger.

### Claim 3 (depends on 1)

The volatile liquid refueling apparatus of claim 1 wherein:
said probe includes an actuator pin which unlocks said safety lock when said probe engages with said receiver.

### Claim 4

A receiver for a volatile liquid refueling apparatus, comprising:
a dual locking mechanism whereby said apparatus can be locked in either an open position or a closed position, and a safety lock which disables or enables access to the dual locking mechanism when manually activated;
whereas said receiver includes a locking plunger assembly, having a plunger with a housing having a plunger slot;
whereas said safety lock unlocks and locks said locking plunger assembly;
whereas said safety lock comprises a lock ramp pin assembly which includes a lock ramp pin having a lock diameter area and a ramp area; and
whereas said lock ramp pin has a ramp pin slot, and is configured such that when said plunger slot and said lock ramp pin slots are aligned, the safety lock is activated and depression of the plunger is prevented and when said plunger slot and said lock ramp pin slots are not aligned, the safety lock is deactivated and depression of the plunger is allowed.

### Claim 5 (depends on 4)

The receiver of claim 4 wherein:
said lock ramp pin assembly includes lock dogs positioned in lock dogs bores, such that when said safety lock is activated, said lock dogs are constrained to contact said lock diameter area of said lock ramp pin and are prevented from release, which prevents depression of said plunger, and when said safety lock is deactivated, said lock dogs allowed to contact said ramp area of said lock ramp pin and are released, which allows depression of said plunger.
