Abstract
The utility model discloses an engine oil pressure extinguisher, belonging to a diesel oil engine component. The technical proposal is that a piston is movably positioned in a shell hollow cavity. The piston is provided with a center oil bore and an oil outlet bore connected with the center oil bore, and the piston and the shell hollow cavity are mutually matched in sealing. One end of the hollow cavity in the shell is provided with a ring bulkhead, and a pre-pressure spring is provided between the ring bulkhead and the piston. The shell is provided with a diesel oil outlet bore corresponding to the ring recess of the oil outlet bore arranged on the piston, and a regulating pressure screw is fastened in the other end of the shell hollow cavity. The contact face of the regulating pressure screw and the shell is provided with a regulating pressure shim, and a hollow screw with a center engine oil through hole is fastened and sealed in the regulating pressure screw. One end of the ring bulkhead is connected in a diesel oil pipeline, and the hollow screw on the other end of the ring bulkhead is connected in an engine oil pipeline. The engine oil pressure is too low or no, and then the oil circuit is closed immediately. Fuel oil is not provided to the engine, so the engine is extinguished to insure the engine against damage. The modified engine oil pressure extinguisher is mainly suited to various diesel oil engines with single cylinder or multiple cylinders.
Description
Technical field
The utility model relates to a kind of diesel engine accessory, is specially a kind of according to the engine oil pressure situation shorting-out device that enforcement is stopped working to motor.
Background technique
All there is a kind of drawback in present diesel engine (single cylinder engine and multi-cylinder engine): the motor of the work of promptly turning round because of certain situation (as in the machine oil shell serious lack that machine oil, the fracture of machine oil pipeline, oil pump damage, the machine oil air silk is loosening or machine oil shell inner engine oil too dirty or the like) only machine oil or engine oil pressure are crossed when low its work of can remaining in operation.If the at this moment untimely engine dies that allow are easy to cause motor catastrophe failure to occur.Engine oil pressure is crossed low or is not supplied machine oil, will cause engine lubrication bad, causes tile kilning thus, the cylinder that rises, serious consequences such as bent axle locking; Particularly singly roll, two single cylinder diesel engine that rolls, in case machine oil only, not only tile kilning, the cylinder that rises also can cause connecting rod to scrap, bent axle is scrapped.Though a kind of engine oil pressure alarm system or engine oil pressure inductor of being equipped with also arranged now, and these devices must have power supply and complicated circuit and instrument display lamp.Do not have maintenance in time in case supply voltage shakiness or circuit break down, the machine oil alarm system will equal zero.
A kind of mechanical type engine oil pressure shorting-out device has been proposed in my Chinese patent application formerly 200320107416.0, though it has solved engine oil pressure effectively and has cut off the diesel oil oil circuit when undesired and realize the auto extinguishing problem, but also there are these defectives, the one, all have automatic decompression device when oil pressure is too high in the machine oil pipeline in the existing diesel, the institute so that high pressure auto extinguishing function become unnecessary; The 2nd, the precompression of spring is the preceding setting of dispatching from the factory, and can't adjust after dispatching from the factory, and when the shorting-out device accumulative total operating time was oversize, loaded spring elastic force diminished, and influences the service behaviour of shorting-out device.
Summary of the invention
The objective of the invention is to overcome the deficiency that above-mentioned prior art exists, and provide a kind of engine oil pressure to cross low or when not supplying machine oil, allow the modified model engine oil pressure shorting-out device of motor auto extinguishing at short notice.
The technical solution of the utility model is this modified model engine oil pressure shorting-out device, it comprises shell and shell inner assembly, be provided with cavity in the described shell, piston is movably located in the cavity, the thin end of piston is provided with the axial centre oilhole, communicating with the center oilhole at the middle part of the thin end of piston also is provided with a pair of oil outlet, and the oil outlet place establishes circular groove; It is cylindric and be sealed and matched mutually with the ladder inner chamber of corresponding shell that piston is ladder; Drive fit has annular that band diesel oil enters the hole silently in the thin termination portion of shell inner cavity, and annular silently and between the corresponding end face of piston is equipped with loaded spring, and the thin end of shell is provided with a pair of diesel oil and portals; Be fastened with hollow voltage regulation screw in the butt end of cavity pocket of outer cover; Sealing is fastened with the cored screw of band center machine oil hole in the hollow voltage regulation screw, a shell band shape end silently is connected in the diesel oil pipeline, the other end cored screw is connected in the machine oil pipeline, it is characterized in that being provided with the pressure regulation pad between hollow voltage regulation screw and the housing contacts face; Diesel oil portals can be provided with the circular groove of oil outlet corresponding with piston.
When motor entry into service work, engine oil pressure just often, piston promotes the lower compression spring and silently holds mobile to annular at engine oil pressure, when the butt end of piston moves to the bottom of shell butt end and when inconsistent with it, this position make circular groove that piston is provided with oil outlet just in time with shell on a pair of diesel oil portal corresponding, diesel oil enters shell inner cavity through an annular end silently, diesel oil on piston center oil duct, oil outlet, circular groove and shell portals and enters the engine fuel supply system, for starting normal use.
Engine oil pressure is crossed low or when not supplying machine oil; piston moves to hollow voltage regulation screw end under the thrust of loaded spring; and it is finally inconsistent with it; this position makes this piston be provided with the dislocation of portalling of the circular groove of oil outlet and a pair of diesel oil on the shell; the sealing of diesel oil oil circuit; can't enter the engine fuel supply system, motor is forced to stop working, autostop.
The invention has the beneficial effects as follows: as long as the diesel engine engine oil pressure is crossed low or when not supplying machine oil, all can cut off the diesel oil oil circuit timely and effectively at once, allow diesel oil can't enter the engine fuel supply system, forced engine is flame-out.Thereby guaranteed that motor avoids infringement, improved the performance of motor, prolonged the working life of motor.The pressure regulation pad that is provided with between hollow voltage regulation screw and the housing contacts face can make the elastic force of the loaded spring in the shorting-out device obtain more by a small margin adjustment, has also strengthened the sealing of hollow adjustment screw and housing contacts face.
