Description
Technical field
The utility model relates to a kind of motor car engine accessory, relates to especially that a kind of volume is less, the plunger type piston cooling device of compact structure.
Background technique
Along with the continuous quickening of industrialization paces, the application area of motor is more and more wider, and market is more and more higher to the requirement of motor, causes motor constantly to be reinforced, and its power improves constantly.Wherein the temperature of piston is a key factor that influences the motor reinforcing degree in the engine working process, when piston temperature too high, when its heat can not in time outwards conduct, problems such as lubricating oil high-temp carbonization between the decline of piston material mechanical property, the piston ring can appear, cause piston distortion, piston scaling loss, piston scraping, the piston ring defective of waiting indefinitely, final result are that engine performance descends even damages.Mode to the piston cooling is: in machine oil oil inlet hole, machine oil oil storage chamber, the machine oil draining hole that the piston crown setting is connected, the cooling unit that fixedly comprises the oil spout structure at motor, wherein oil spout structure comprises nozzle carrier and nozzle, the oil inlet hole that the jet of nozzle is aimed at piston crown sprays machine oil, machine oil enters in the oil storage chamber, flow out the heat of taking away piston from the vent piston oilhole then, to reduce the operating temperature of piston.
Distinguish from valve core structure, at present piston cooling device has two kinds of steel ball type and plunger types.For the plunger type cooling unit, at present common is two style structure, and the cooling unit volume of this structure is bigger, need take bigger installing space, can not use at the motor of float amount compact structure, service condition is comparatively harsh, has certain narrow limitation.And for the steel ball type piston cooling device, be to utilize its inner steel ball to open and close, reach the purpose that oil circuit opens and closes, as notification number be: a kind of engine piston cooling jet that the Chinese model utility of CN202187818U provides, comprise nozzle body, nozzle body is provided with the cavity of end sealing, the cavity the other end be diameter less than the oil duct of cavity, be provided with steel ball and spring in inside cavity; One side of steel ball is stuck on the oil duct of cavity, and opposite side and spring one side are joined; The opposite side of spring with and the nut that is tightly connected of cavity join; Be arranged with two jet pipes that are communicated with cavity at nozzle body; Cavity is cross structure.The piston cooling device that this patent is mentioned is the steel ball type structure, because the stressed instability of steel ball, in actual use, play takes place steel ball easily, causes sealing relatively poor, also has certain narrow limitation.
The model utility content
The utility model mainly is bigger at the existing volume of existing plunger type piston cooling device, it is bigger to take up room, the problem that can not use at small displacement engine, provide a kind of volume less, compact structure, equal plunger type piston cooling device of adaptable compact structure on large and small displacement engine.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of plunger type piston cooling device of compact structure, comprise the valve body that is communicated with the engine cylinder-body cooling channel, be connected with spray bar on the valve body, be provided with mounting hole in the described valve body, be provided with lining in the mounting hole, described lining is that snap-fit is connected with valve body, the sidewall of lining is provided with the oil-through hole that is communicated with spray bar, be provided with the spool that has that makes the oil-through hole sealing in the lining, spool and lining are for being slidingly connected, be installed with limiting stopper in the mounting hole, be provided with the compression spring between limiting stopper and the spool.Under the situation of no oil pressure, spool is tightly fitted with lining under the active force of compression spring, and makes oil-through hole seal.Machine oil in mounting hole is more and more, and this moment, oil pressure will be greater than the yield force of compression spring, the compression of compression spring, spool moves under the active force of oil pressure, and oil-through hole is opened, and machine oil can enter in the spray bar by oil-through hole, be ejected into piston base through spray bar, piston is cooled off.This piston cooling device is integral structure, contacts closely between each building blocks of function, and volume is less, compact structure, and installing space takies less, thereby all can use on large and small displacement engine.
As preferably, described spool is the solid of rotation that the cross section is " U " shape, and limiting stopper is provided with draw-in groove, and an end of compression spring is connected in the described draw-in groove, and the other end is connected on the bottom land of spool.The two ends of compression spring are connected in two grooves, connect and stablize, and are difficult for losing efficacy.
As preferably, be provided with first attachment hole and second attachment hole in the described lining, first attachment hole is connected by the inclined-plane with second attachment hole, described oil-through hole is communicated with first attachment hole, described spool and compression spring all are arranged in first attachment hole, and the aperture of first attachment hole is greater than the aperture of second attachment hole.
As preferably, the end of described spool is provided with the breach of annular along last radial direction along spool, described breach is arranged on the spool towards an end of second attachment hole, and the outer side wall of spool is connected with the hole wall of first attachment hole, is resisted against on the described inclined-plane towards the end of second attachment hole on the spool.Spool near the end of second attachment hole along on breach is set, the end of spool is stepped along constituting like this, by stepped end along respectively with hole wall and the inclined-plane butt of first attachment hole, thereby constituted the two seals point, sealing is tight, if owing to technology is made reason, wherein one seal point lost efficacy, and another road seal point also can play good sealing effect.
As preferably, be installed with mounting plate on the outer wall of described valve body, mounting plate is provided with bolt hole, and mounting plate is connected by bolt and engine cylinder-body.Valve body is fixed on the engine cylinder-body by mounting plate.
As preferably, the outer wall of described valve body is provided with annular groove, is connected with seal ring in the annular groove.Seal ring seals, and prevents leakage of oil.
As preferably, be provided with vent in the middle part of the described limiting stopper.Along with the movement of spool, the space between spool and the limiting stopper constantly changes, so at limiting stopper vent is set, keeps the external and internal pressure unanimity, and spool moves smooth and easy.
Therefore, the beneficial effects of the utility model are: contact closely between each building blocks of function of this piston cooling device, volume is less, compact structure, and installing space takies less, thereby all can use on large and small displacement engine.
