Abstract
A pressure releasing valve capable of reserving air pressure is formed with a pressure reserving chamber to retain a proper amount of air pressure in the pressure releasing valve when the engine is changing from an accelerating and increasing pressure condition to a condition of running idly and releasing pressure, so that when the engine accelerates and increases pressure again, air of the condenser can be continually supplied for the engine to let it run comparatively smoothly in accelerating, not only economizing energy but ensuring safety as well.
Claims6
A pressure releasing valve capable of reserving air pressure comprising an air tube connecter, a left cover, a first valve trip, an air chamber holder, a second valve trip, a casing, a shaft rod and a right cover;
- Said left cover provided inside with a chamber for receiving a left stop member, a right stop member and a spring, said spring sandwiched between said left and right stop members, a first valve sheet mounted on the rear side of said right stop member and sandwiched by a gasket of said air chamber holder and said right stop member;
- Said air chamber holder having a lengthwise through hole and a lateral hole, said air chamber holder fitted around with a sleeve and an O-shaped ring, said air chamber holder fitted around with two leakage preventive rings between opposite openings of said lengthwise through hole;
- Said casing consisting of a left casing, an intermediate casing and a right casing, said three casings respectively formed with an air intake passage communicating with one another, said three casings combined together by means of long bolts;
- A second valve sheet sandwiched by said left casing and said intermediate casing, with a pressure reserving chamber formed between said second valve strip and said left casing;
- Said shaft rod positioned between said intermediate casing and said right casing, said shaft rod having its left end inserted through said second valve sheet and fixed by a ring, a left stop member and a spring orderly disposed on the right side of said second valve sheet, said spring having one end fitted in the spring holder of said intermediate casing, said shaft rod fitted around with a sleeve to be fitted in the central hole of said intermediate casing, said shaft rod having its right end combined with a right stop member and tightly secured together by a bolt, said right stop member deposited in the central hole of said right casing and resisted by a leakage preventive ring;
- Said right side cover provided with an air tube connecter on the right side and a circular rim on the left side for a ring to be mounted around and fixed therein, said circular rim combined with said right casing by means of bolts.
