Abstract

The utility model relates to a pressure-reducing automatic return device for diesel engines. The utility model comprises a pressure-reducing cam shaft, a pressure-reducing cam, a pressure-reducing shaft sleeve, a pressure-reducing handle, a valve rocker, etc., and is characterized in that the utility model also comprises a ratchet wheel, a ratchet pawl, a spacing ball, a spacing baffle plate, a pressure-reducing adjusting spring, etc., wherein, the ratchet wheel is arranged on the pressure-reducing cam shaft; the back end of the ratchet wheel is provided with the pressure-reducing shaft sleeve; the ratchet pawl is fixed above the ratchet wheel at the upper end of the valve rocker; the spacing baffle plate is sheathed on the pressure-reducing shaft sleeve; spacing groove is positioned above the spacing baffle plate, and a locking nut is positioned behind the spacing baffle plate; the pressure-reducing handle in which the spacing ball and the pressure-reducing adjusting spring is positioned behind the locking nut; the spacing ball is clamped in the front of the pressure-reducing handle. The utility model has the advantages of convenience and labor saving at the time of starting and repair.

Description

Diesel engine decompression automatic resetting device

The utility model belongs to a kind of diesel engine decompression automatic resetting device.

Single cylinder diesel is except that electricity starts, when starting, all handy manual control decompression plate stem, and can only use another arm rocking-turn motor, it is very painstaking to start up, especially 1100 types that assembled on present agricultural vehicle, 1110 diesel engines, because the cylinder barrel diameter is big, compressive force is big, require great effort more during startup, sometimes also can cause the diesel engine counter-rotating, drive the crank rotation, therefore often have casualty accident to take place.

The purpose of this utility model provides a kind of without manual control decompression tommy bar, and automatic resetting device can reduce pressure with the diesel engine of two arm rocking-turn ato units.

The utility model comprises relief cam axle, relief cam, decompression axle sleeve, decompression handle, valve rocker etc., relief cam is fixed on the front end of relief cam axle, is characterized in that it also comprises ratchet, ratchet, tightening nut, spacing ball, postive stop baffle, decompression adjustment spring etc.Ratchet is installed on the relief cam axle, the rear end is a decompression axle sleeve, ratchet is fixed on the upper end of valve rocker, ratchet is positioned at the top of ratchet and can contacts with it, there is a hole at the center of postive stop baffle, restraining groove is arranged on the lower surface, the center hole of postive stop baffle is enclosed within on the decompression axle sleeve, the rear end is a locking nut, decompression handle is installed in the rear end of locking nut, on the relief cam axle, spacing ball and decompression adjustment spring are housed in the decompression handle, the rear end that spring is adjusted in decompression is to adjust bolt, spacing ball is stuck on the decompression handle front edge, and is positioned at the below of postive stop baffle and contact with it.

The utility model has solved diesel engine starting and rocking-turn all need be with the reduce pressure problem of tommy bar of a manual control when repairing, can be with two hand traverse ato units, and laborsaving, safety, and simple in structure.

Embodiment:

The utility model comprises relief cam axle 2, relief cam 13, decompression axle sleeve 6, decompression handle 10, valve rocker 4 etc., one end of relief cam 13 is protruding, the other end is flat, be fixed on the top of relief cam axle 2, it also includes ratchet 1, ratchet 3, tightening nut 5, spacing ball 7, postive stop baffle 8, decompression adjustment spring 9 etc.Ratchet 1 is installed on the relief cam axle, and its rear end is a decompression axle sleeve 6, and an end of ratchet 3 is fixed on the upper end of valve rocker 4, and ratchet 3 also is positioned at the top of ratchet 1, and can contact with ratchet, and ratchet 1 all is enclosed in the valve cover with valve rocker 4.Postive stop baffle 8 centers are porose, and three restraining grooves are arranged on the lower surface, and the center hole 12 of postive stop baffle 8 is enclosed within the bottom of decompression axle sleeve 6, rear end nut 5 locking that is locked.Decompression handle 10 is installed on the rear end, relief cam axle 2 of locking nut 5, spacing ball 7 and decompression are housed in the decompression handle 10 adjust spring 9, spacing ball 7 is stuck on decompression handle 10 front edges, and being positioned at the below of postive stop baffle, the rear end that spring 9 is adjusted in decompression withstands on to be adjusted on the bolt 11.

Working principle:

During ato unit, rotate counterclockwise decompression handle 10, spacing ball 7 is stuck in the enable position groove 14 below the postive stop baffle, just can start diesel engine with two hand traverses, decompressor just can turn to running position groove 15 automatically, and need not decompressor with handgrip, when repairing diesel engine, spacing ball is snapped in the repair location groove 16 below the postive stop baffle, just can arbitrarily rotate diesel engine.
