Abstract
The invention discloses a pressure-adjustable engine oil filter. A pressure adjusting valve is composed of a valve seat, a steel ball, a pressure adjusting bolt, a spring and the like which are fixed on a valve body, the pressure adjusting bolt is fastened with the valve body via a nut, and the valve body is integrally fixed with an engine oil filtering pot. An engine oil inlet on the valve body is communicated with the pressure adjusting valve, and when engine oil pressure does not reach set pressure, the pressure adjusting valve is turned off, and engine oil enters the engine oil filtering pot, flows out via an engine oil outlet on an engine oil filtering seat after being filtered and then enters a main engine oil way of an engine. When pressure at the engine oil inlet exceeds the set pressure, the pressure adjusting valve is turned on, and the engine oil flows back to an engine oil pool of the engine via an engine oil return port (of the pressure adjusting valve). The engine oil pressure is set or adjusted by adjusting the pressure adjusting bolt (by adjusting compression force of the spring). The pressure-adjustable engine oil filter has the advantages of convenience in replacement, low usage cost and the like.
Description
Technical field
The invention belongs to engine components, be specifically related to a kind of device of use for diesel engine machine oil purification filtering.
Background technique
The oil filter that is assemblied at present on the high speed engine substantially all is rotatable filter, and the engine oil pressure of this kind filter cleaner can not be regulated, if desire is regulated the engine oil pressure in the motor main oil gallery, will pressure regulator valve be installed again at body.The motor that has can increase design at body add pressure regulator valve, but the motor that has then can not because be subjected to the restriction in external engine space, be difficult to pressure regulator valve is added on the body.If a kind of oil filter that has regulator is provided for this reason, then the motor for the compact class of space outerpace has solved oil pressure adjusting problem.
Summary of the invention
The objective of the invention is, at the motor that can not arrange pressure regulator valve on the body, provide a kind of device that can regulate the main oil gallery oil pressure by oil filter.
Below in conjunction with accompanying drawing structural principle of the present invention is described.The oil filter of adjustable in pressure has: oil strainer filling, valve body, valve seat, firm ball, locknut, pressure regulation double-screw bolt, spring and seal ring etc., valve body is provided with filler opening, oil outlet and return opening.By be fixed on valve seat on the valve body, just ball, locknut, pressure regulation double-screw bolt, spring are formed pressure regulator valve, valve body and oil strainer filling are fixed as one.Be equipped with valve seat, firm ball, spring pressure regulation double-screw bolt and seal ring in the valve body successively, by locknut that pressure regulation double-screw bolt and valve body is fastening.
Its principle is that the filler opening on the machine oil filter block is communicated with pressure adjusting pressuring valve, and before engine oil pressure did not reach the pressure of setting, pressure regulator valve cut out, and machine oil enters in oil strainer irritates, and the oil outlet from the machine oil filter block flows out after filtering, enters the main oil gallery of motor.When the pressure of filler opening surpassed setting pressure, pressure adjusting pressuring valve was opened, and machine oil flow back in the oil sump of motor by (pressure adjusting pressuring valve) return opening.By regulating (impacting force of spring) pressure regulation double-screw bolt, set or regulate engine oil pressure.
Characteristics of the present invention and beneficial effect are, to filter with voltage regulation function and integrate, when realizing filtering machine oil, can also realize the adjusting of engine oil pressure, solve pressure regulator valve design space-constrained difficult problem on body, can be widely used on the motor of the compact class of space outerpace.
Description of drawings
Fig. 1 is surface structure sketch of the present invention.
Fig. 2 also is the A-A sectional drawing of Fig. 1 for the inner theory structure sketch of the present invention.
Fig. 3 is working oil path schematic representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing and by embodiment structure of the present invention is described further.The oil filter of adjustable in pressure, its structure are that valve body 2 is provided with filler opening 3, oil outlet 4 and return opening 5.By being fixed on the valve seat 6 on the valve body, firm ball 7, locknut 8, pressure regulation double-screw bolt 9, spring 10 decomposition pressure modulating valve, valve body and oil strainer are irritated 1 and are fixed as one.Be equipped with valve seat, firm ball, spring pressure regulation double-screw bolt and seal ring 11 in the valve body successively, by locknut that pressure regulation double-screw bolt and valve body is fastening, the filter core separation (Fig. 1) in filler opening and oil outlet are irritated by filter.Filler opening communicates with pressure regulator valve by firm ball, return opening is located at the rear of firm ball in the pressure regulator valve, namely form way to cycle oil by filler opening, return opening, when engine oil pressure surpassed setting value, machine oil was got back to motor oil sump (Fig. 2) from filler opening through the return opening of valve seat.By filler opening, oil strainer irritate, oil outlet forms working oil path, when engine oil pressure during smaller or equal to setting pressure, enters the main oil gallery (Fig. 3) of motor after the filter core 12 in machine oil is irritated through oil strainer from filler opening filters from oil outlet.
For present embodiment, the machine oil filter block adopts die casting aluminium to make, and valve seat adopts steel to insert, and machines after the die casting.Oil strainer irritate to adopt rotation fitting type, and after using certain hour or car and running to certain milimeter number, the oil strainer that more renews is irritated, and the machine oil filter block need not changed, and the machine oil filter block adds sealing gasket by bolt and is fixed on the body.On structural design: the pressure regulation valve body is designed on the machine oil filter block, the machine oil filter block is made of aluminium, consider the operational safety of pressure regulator valve, adding a steel when the casting filter block inserts as valve seat, the four directions is made in the outer end of pressure regulation double-screw bolt, is used for regulating the screw-in back-out of pressure regulation double-screw bolt, and the pressure regulation double-screw bolt mixes up the back and fixes with locking nut, with the sealing of combination seal pad, prevent leakage of oil between locking nut and valve body.
