Abstract
The utility model relates to a self control protector for the machine oil under-pressure of an engine, which comprises a housing, a piston, a piston spring, a back cover, etc. The utility model is characterized in that a machine oil port is arranged on the housing, an annular groove is arranged on the middle part of the piston, a fuel inlet and a fuel outlet are corresponding, and the fuel inlet and the fuel outlet are arranged on corresponding both sides of the housing. An adjusting screw is arranged on the back cover, and the front end of the housing is provided with a clutching switch. Embodiment adopts a T-shaped cylinder piston, and a corresponding piston hole. The utility model has the advantages of self control protective function, high safety; accordingly, the condition that the injury of lubricating components lead to the damage of lubricating components can not happen, and the condition is caused by having no engine oil or lacking the engine oil; the utility model has the advantages of small size, compact structure, easy installation, etc.
Description
The utility model relates to a kind of engine protector, particularly a kind of engine motor oil decompression auto-control protective device.
In the prior art, generally all be to adopt measuring instrument to indicate oil level.Measuring instrument has only deixis and the unprotect function, even when indicating inorganic oil, motor is running as usual but, in addition when machine oil is not enough, very easily causes lubricated component damage so that damage, until the generation accident.
When providing a kind of machine oil decompression, the purpose of this utility model can supply with the engine motor oil decompression auto-control protective device that motor is decommissioned by automatic fuel shut-off.Its technical solution comprises: housing, piston, piston spring and bonnet etc., main points are: the housing before the piston is provided with the machine oil mouth, the piston middle part is provided with annular groove, being provided with two corresponding fuel oils with corresponding housing both sides, annular groove position imports and exports, on bonnet, establish the adjusting screw that energy regulating piston spring is housed, Isolating Switch is housed at the housing front end.
The utility model not only has the auto-control protective function, and is safe and reliable, and the lubricated component in the motor damages because of inorganic oil or machine oil are not enough so that damage; It is little also to have volume, compact structure, advantage such as Applicable scope is big, and is easy for installation.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in detail:
Accompanying drawing is a structural representation of the present utility model.
As long as the machine oil mouth (10) that is arranged on T cylinder piston (5) the place ahead housing (6) among the figure is joined with the main oil gallery of engine motor oil pump output terminal; and the fuel pipe before engine fuel pump intake and the fuel pump is connect respectively in the fuel oil import and export (8) of even two correspondences that are provided with in housing (6) both sides in the drawings, present embodiment just can play the effect of machine oil decompression auto-control protective.After engine start, when machine oil is enough measured, the pressure that oil pump produces just can fully act on the front-end face of T cylinder piston (5) by the machine oil of enough amounts, promote T cylinder piston (5) extrusion piston spring (4), T cylinder piston (5) is put in place, make the annular groove (7) that is arranged on T cylinder piston (5) mast middle part coincide with the fuel oil import and export (8) that are arranged on housing (6) relevant position, both sides, the fuel oil road connects (as accompanying drawing); Not enough or when not having when oil level; the pressure that oil pump produces just can't act on the front-end face of T cylinder piston (5) by machine oil; piston spring (4) is upheld naturally; promote T cylinder piston (5); making annular groove (7) and fuel oil import and export (8) staggers; cut off the fuel delivery of motor, made its shutdown, too little or inorganic oil does not damage so that damage because of machine oil thereby make lubricated component.Obviously, the piston among the figure (5) also can adopt the cylinder piston; Adopting T cylinder piston (5) and corresponding piston hole among the figure, is for fear of because of engine oil pressure is excessive the piston (5) that puts in place being continued to promote to cause improper dislocation again, guaranteeing that the fuel oil road fully connects as long as machine oil is enough measured.For the utility model can be applicable in the motor of different engine oil pressures, in bonnet (3), also be provided with the adjusting screw (1) of energy regulating piston spring (4); Simultaneously, on adjusting screw (1), be provided with positioning screw cap (2), make adjusting screw (1) location of adjusting.Start the function quick starting for making, the front end of housing (6) is equipped with Isolating Switch, and Isolating Switch is made of clutch housing (12), clutch plunger (9), clutch spring (11) and clutch for clutch control part (13); When closing, clutch plunger (9) relies on clutch spring (11) to shift piston (5) onto position, makes the fuel oil road connect (as shown in drawings); During separation, the end surface of clutch plunger (9) resets to the edge, front of machine oil mouth (10), makes this protector be in normal working.
Claims (3)
1, a kind of engine motor oil decompression auto-control protective device; comprise housing (6), piston (5), piston spring (4) and bonnet (3) etc.; it is characterized in that: the preceding housing (6) of piston (5) is provided with machine oil mouth (10); the middle part of piston (5) is provided with annular groove (7); and the fuel oil that is provided with correspondence on corresponding housing both sides, same annular groove (7) position is imported and exported (8); bonnet (3) is provided with adjusting screw (1), and the front end of housing (6) is provided with Isolating Switch.
2, a kind of engine motor oil decompression auto-control protective device according to claim 1; it is characterized in that: piston (5) is a T cylinder piston; annular groove (7) is located at the mast middle part of T cylinder piston (5), and the piston hole in the housing (6) also correspondingly is made as the T cylinder.
3, engine motor oil decompression auto-control protective device according to claim 1 and 2, it is characterized in that: adjusting screw (1) is provided with positioning screw cap (2).
