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

1 . A fluid supply apparatus comprising a supply system for transporting fluid in a housing main body while measuring flow rate of the fluid; a control mechanism for controlling the supply system; a hose introduced from the supply system and having a nozzle at an end thereof; and a signal line along the hose, wherein said signal line is detachable.

2 . The fluid supply apparatus as claimed in claim 1 , wherein the signal line includes a detachable portion as a separable portion, and the detachable portion is provided with a locking mechanism.

3 . The fluid supply apparatus as claimed in claim 2 , wherein an emergency separation mechanism is mounted to release the locking mechanism.

4 . The fluid supply apparatus as claimed in claim 1 , wherein the locking mechanism includes a signal line holding member, to the signal line holding member is mounted a first convex portion for releasing engagement of the locking mechanism, and the locking mechanism includes a lock releasing member, and to the lock releasing member is mounted a second convex portion for releasing engagement of the locking mechanism by contacting the first convex portion.

5 . The fluid supply apparatus as claimed in claim 4 , 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 4 , 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.

7 . The fluid supply apparatus as claimed in claim 2 , wherein the locking mechanism includes a signal line holding member, to the signal line holding member is mounted a first convex portion for releasing engagement of the locking mechanism, and the locking mechanism includes a lock releasing member, and to the lock releasing member is mounted a second convex portion for releasing engagement of the locking mechanism by contacting the first convex portion.

8 . The fluid supply apparatus as claimed in claim 7 , 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.

9 . The fluid supply apparatus as claimed in claim 7 , 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

10 . The fluid supply apparatus as claimed in claim 3 , wherein the locking mechanism includes a signal line holding member, to the signal line holding member is mounted a first convex portion for releasing engagement of the locking mechanism, and the locking mechanism includes a lock releasing member, and to the lock releasing member is mounted a second convex portion for releasing engagement of the locking mechanism by contacting the first convex portion.

11 . The fluid supply apparatus as claimed in claim 10 , 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.

12 . The fluid supply apparatus as claimed in claim 10 , 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
