Hydrogen fuel dispenser with pre-cooling circuit
First Claim
1. A hydrogen fuel dispenser, comprising:
- a nozzle for engaging and dispensing hydrogen fuel to a receptacle, the nozzle including a nozzle line, disposed within a nozzle body, through which hydrogen fuel is dispensed to the receptacle;
a fueling line connecting the nozzle line to a hydrogen fuel storage for communicating hydrogen fuel from the hydrogen fuel storage to the nozzle line, the fueling line connecting to the nozzle line within the nozzle body;
a pre-cooling line connected to the fueling line downstream from the hydrogen fuel storage, within the nozzle body, for pre-cooling hydrogen fuel; and
a flow-path selector provided at a connection between the fueling line and the pre-cooling line within the nozzle body, the flow-path selector selectively;
blocking hydrogen fuel flow between the fueling line and the pre-cooling line while opening hydrogen fuel flow between the fueling line and the nozzle line; and
opening hydrogen fuel flow between the fueling line and the pre-cooling line.

Abstract
A hydrogen fuel dispenser includes a pre-cooling circuit, a hydrogen fuel storage for storing hydrogen fuel, a nozzle for dispensing hydrogen fuel to a receptacle, and a fueling line connecting the hydrogen fuel storage to the nozzle for communicating hydrogen fuel from the hydrogen fuel storage to the nozzle. The pre-cooling circuit is provided to cool hydrogen fuel in the fueling line, and includes a pre-cooling line connected to the fueling line downstream from the hydrogen fuel storage, and a flow-path selector provided at a connection between the fueling line and the pre-cooling line. The flow-path selector selectively: blocks hydrogen fuel flow between the fueling line and the pre-cooling line while opening hydrogen fuel flow between the fueling line and a nozzle line of the nozzle; and opens hydrogen fuel flow between the fueling line and the pre-cooling line.
