Description

Technical Field

[0001] The utility model relates to the field of an engine starting valve, in particular to a diesel engine starting valve. Background Art

[0002] The starting valve generally consists of a return valve spring, an upper control air chamber, a lower compressed air chamber, a valve stem, and a valve housing. It's typically mounted on the cylinder head. How it works: When the cylinder receives a control air pressure signal, the valve stem moves downward, opening the compressed air valve. Compressed air enters the top of the expanding piston, pushing it downward. This rotates the crankshaft, pushing the other pistons to perform compression and ignite, starting the engine.

[0003] During operation, the automobile starting valve adopts the traditional negative pressure push cylinder method, which does not have auxiliary rebound. It will cause the reaction force generated by the release of energy from the spark plug igniting the oil to damage the stabilizing rod. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The utility model adopts the method that oil is introduced into the cavity through the oil inlet pipe, and is located between the push column connected to the top of the push rod and the pressure plate. The connecting block fixed on the inner frame wall of the connecting plate is used to position the fixed shaft. When the fixed shaft rotates, it will drive the hinge seat to flip, and the spring hinged at one end of the hinge seat will squeeze the pressure plate. The oil between the pressure plate and the push column will expand after ignition, and push the push rod to move in the cavity mouth of the cavity, thereby driving the rotation of the eccentric block. The rotating shaft connected to the eccentric part of the eccentric block will rotate, and its structure is more optimized and the design is more reasonable. BRIEF DESCRIPTION OF THE DRAWINGS
