Abstract

To provide a fluid supply apparatus capable of preventing inconveniences cause by cut of a signal line when a filling hose is separated through an emergency separation pipe joint. The fluid supply apparatus (100: fluid supply apparatus for supplying fluid such as hydrogen gas and gasoline) includes a supply system for transporting fluid such as hydrogen gas and gasoline in a housing main body while measuring flow rate of the fluid; a control mechanism for controlling the supply system; a hose (2) introduced from the supply system and having a nozzle (1) at an end thereof; and a signal line (3) along the hose (2), wherein the signal line (3) is detachable.

First claim

What is claimed is:

1. A fluid supply apparatus for transporting fluid from a hydrogen dispenser while measuring and controlling a flow rate of the fluid, the fluid apparatus comprising:
a hose introduced from the hydrogen dispenser and having a nozzle at an end thereof; and
a signal line along the hose, wherein said signal line is detachable and includes a detachable portion as a separable portion, the detachable portion being provided with a locking mechanism which includes:
a signal line holding member having a first convex portion mounted thereto; and
a lock releasing member having a second convex portion mounted thereto for facilitating the release of the detachable portion of the locking mechanism by contacting the first convex portion.

2. The fluid supply apparatus as claimed in claim 1 , wherein an emergency separation mechanism is mounted to release the locking mechanism to facilitate the selective release of the detachable portion thereof.

3. The fluid supply apparatus as claimed in claim 2 , wherein on both sides of the first convex portion in a circumferential direction are formed detent projections, and dimension of the second convex portion in the circumferential direction is smaller than a gap between the detent projections.

4. The fluid supply apparatus as claimed in claim 2 , wherein on both sides of the first convex portion in a circumferential direction are not formed detent projections, and the second convex portion is formed on a whole area of the lock releasing member in a circumferential direction.

5. The fluid supply apparatus as claimed in claim 1 , wherein on both sides of the first convex portion in a circumferential direction are formed detent projections, and dimension of the second convex portion in the circumferential direction is smaller than a gap between the detent projections.

6. The fluid supply apparatus as claimed in claim 1 , wherein on both sides of the first convex portion in a circumferential direction are not formed detent projections, and the second convex portion is formed on a whole area of the lock releasing member in a circumferential direction.
