Abstract
The utility model relates to an engine oil protector for a diesel oil filter, belonging to a protection device for an engine. The utility model is composed of a plunger, a regulating spring, a sectional casing for a protector and a filter, an operating handle, etc. The utility model is characterized in that the sectional casing for a protector and a filter is provided with an oil inlet hole, a fuel oil path, an engine oil pressure oil channel, and an oil returning hole of a diesel oil filter. The plunger is sheathed with the regulating spring and the sleeve barrel of the plunger to be arranged in the sectional casing for a protector and a filter. The utility model has the advantages of simple structure and low manufacture cost. When oil pressure of lubricating oil is too low, the supply of fuel oil can be quickly and automatically cut off, and an engine forcibly stops running right away, which can prevent an accident from happening. The engine oil protector for a diesel oil filter is a safe protecting device.
Description
The utility model relates to a kind of novel diesel fuel filter clear oil guard device, is used for that the diesel engine oil pressure reduces to report to the police and the device of autostop, belongs to engine protection device.
At present, there are many vehicles in use intact because of lubricated oil leakage, oil duct stops up, reasons such as oil pump damage cause in the engine running because of unlubricated oil accelerated wear test and cause parts to burn out, cause major accident that generation is often arranged, buy on the particularly present market, the agricultural tricycle that runs on the road, their power all derives from agricultural equipment Diesel engine, and agricultural equipment Diesel engine engine oil pressure display unit does not mostly have fuel level indicator, and has only a pressure display unit, this pressure display unit also is mounted in above the cylinder head of diesel engine, the mounting point of diesel engine on tricycle be again cylinder head backwards, engine oil pressure display device on the cylinder head is just stretched below the compartment like this, make the driver in driving, can't see the engine oil pressure display device below the compartment, if break down in the lubrication system of motor like this, because of lubricated oil leakage intact, oil duct stops up, and reasons such as oil pump damage cause that motor burns out that to cause accident to take place just inevitable.
The purpose of this utility model is: design a kind of simple in structurely, cross when low at the lubricant oil oil pressure, automatic fuel shut-off supply rapidly forces motor to shut down at once, the diesel fuel filter clear oil guard device of protection motor.
The purpose of this utility model is to realize like this, it is mainly by alarm switch contact bolt (1), plunger guide bush (7), plunger (8), Regulation spring (9), filter cleaner protector combination housing (10), cored screw with cover (11), operating grip (13), cored screw compositions such as (16), it is characterized in that: filter cleaner protector combination housing (10) is provided with oil inlet hole (14), fuel oil road (15), engine oil pressure oil duct (17) and diesel-oil filter spill port (22), be installed in behind plunger (8) suit adjusted spring (9) and the plunger guide bush (7) in the filter cleaner protector combination housing (10), one end of filter cleaner protector combination housing (10) has been screwed cored screw with cover (11), the other end of filter cleaner protector combination housing (10) is equipped with alarm switch contact bolt (1), be set with insulation tube (4) on the alarm switch contact bolt (1), felt pad (3) is equipped with in the termination of alarm switch contact bolt (1), cored screw (16) is screwed on the filter cleaner protector combination housing (10), alarm switch contact bolt (1) is gone up rotation set nut (2) and felt pad (3), operating grip (13) is installed on the plunger (8) by pin (12), and positioning wire (20) is installed on the filter cleaner protector combination housing (10) by retaining screw (18) and packing ring (19); Its feature also is: plunger (8) is provided with plunger master oil groove (5) and the standby starting oilhole of plunger (6), and plunger guide bush (7) is provided with sleeve oilhole (21).
The utility model compared with prior art, it is simple in structure, low cost of manufacture; cross when low at the lubricant oil oil pressure, automatic fuel shut-off supply rapidly forces motor to shut down at once; can improve engine life, the accident that prevents takes place, and is a kind of safety protection device.
