US Patent:

53380690, Aug 16, 1994

Filed:

Apr 28, 1993

Appl. No.:

8/054441

Inventors:

Daniel F. McCarthy - Beechhurst NY

Assignee:

Scully Signal Company - Wilmington MA

International Classification:

F16L 3500

US Classification:

285 38

Abstract:

A coupler has a locking mechanism which comprises a J-shaped blocking pin which is attached to a housing. A spring urges the blocking pin towards a locking arm so that a pin end traps the arm between the housing and the pin end to hold the arm in a locked position. The spring may be manually compressed to cause the pin end to move away from the arm so that the arm can swing outward to an unlocked position. The protruding pin end is bevelled and the locking arm has a bevelled portion which mates with the bevelled pin end. As the locking arm is swung to its locked position, the blocking pin end is pushed away from the arm allowing the arm to pass freely by the pin end. After the locking arm has passed over the pin end, the pin end is drawn toward the arm by the spring capturing the arm in the locked position.

Appl. No.:

International Classification:

F16L 5507

US Classification:

137312

Abstract:

A valve includes a plunger which is movable by actuating means such as a solenoid coil, air pressure or other means to move a valve member toward and away from a valve seat. The fluid flow area of the valve is sealed from the actuating means by the diaphragm, O-rings or other forms of sealing structure. In order to insure against leakage past the diaphragm or seal and especially against leakage into the actuating means, the construction includes another diaphragm or seal spaced from the first seal providing a seal space between the first and second diaphragms or seals. In the event of leakage past the first sealing means, flow of the liquid into the space between the first and second sealing means causes an outward flow of the fluid through a detecting passage which thereby provides means which disclose the leakage past the first sealing means so that the first sealing means can be immediately replaced before any damage to the actuating means or to the system itself.
