Abstract
The utility model relates to a rotary valve actuating mechanism of four-stroke internal combustion engine having a spiral oil passage, which comprises a valve body and a cylindrical rotary valve plug arranged inside the valve; the valve plug is provided with an intake passage and an exhaust passage; a spiral groove is arranged on the circumferential surface of the valve plug of the periphery of the exhaust passage; the valve is provided with a feeding passage and an outlet passage which are respectively communicated with the spiral groove. A spiral oil passage which is composed of an intake passage, a spiral groove and an outlet passage can implement effective cooling and lubrication to the rotary valve actuating mechanism.
Description
Technical field
The utility model relates to the rotary distribution device of a kind of quartastroke engine.
Technical background
The principle of traditional four-stroke internal combustion engine distribution mechanism is basic identical, structure is also similar, generally comprise inlet and outlet door, valve guide bushing, valve spring, camshaft, rocking arm, timing sprocket (or timing gear), timing chain (or push rod) etc., the distribution device motion of this kind structure is impacted greatly, operating noise is big, the power in-fighting is big and the raising of restriction internal-combustion engine rotational speed.
The revolution axis type distribution device of Chu Xianing has solved the above-mentioned defective of traditional combustion engine distribution device to a great extent in recent years, the distribution device of this kind structure mainly comprises valve body and is positioned at the cylindrical body rotary spool of valve body, spool is parallel with bent axle and by the bent axle driven rotary, on spool, offer the gas-entered passageway and the exhaust passage that can be communicated with the firing chamber, Structure of Internal-Combustion Engine with this kind distribution device is simple, component are few, operate steadily and noise little.
But the distribution device of this kind structure will be because the high-temperature gas in the spool high speed rotating in valve body, particularly exhaust passage will cause the temperature of spool too high, if spool can not get effectively cooling and lubricated, will influence the normal operation of distribution device.
The model utility content
The purpose of this utility model provides a kind of rotary distribution device of quartastroke engine with screw lubrication oil duct, can access effective cooling and lubricated to guarantee this distribution device that comprises rotary spool.
The rotary distribution device of quartastroke engine with screw lubrication oil duct described in the utility model, comprise valve body and the cylindrical body rotary spool that is positioned at valve body, spool is parallel with bent axle and by the bent axle driven rotary, on spool, offer the gas-entered passageway and the exhaust passage that can be communicated with the firing chamber, on the spool circumferential surface of periphery, exhaust passage, offer spiral chute, offering oil input channel and oil road on valve body is communicated with this spiral chute respectively, the spiral fluted rotation direction should make when spool rotates, spiral chute pushes lubricant oil wherein to oil road, make this oil input channel, spiral chute and oil road are formed the screw lubrication oil duct of this distribution device
Offering circular groove respectively at described spiral fluted two ends is communicated with this spiral chute, wherein a circular groove is communicated with oil input channel, another circular groove is communicated with oil road, to guarantee that in the spool high speed rotating oil input channel and oil road can remain with spiral fluted and well be communicated with.
The oil outlet of described oil road is opened in and is installed in the adjacent valve body end face of timing sprocket of spool end, makes from the lubricant oil of oil outlet ejection to be ejected on the timing sprocket.
The spiral chute that the utility model is offered on the rotary spool circumferential surface, its two ends respectively be opened in valve body on oil input channel and oil road be communicated with, and make this oil input channel, spiral chute and oil road form the oil leab of this distribution device.Because this spiral chute is opened on the spool circumferential surface of periphery, exhaust passage, the spiral fluted lubricant oil of flowing through will be taken away a large amount of engine exhaust heats, thereby spool is effectively cooled off; And make it have the function of oil pump owing to having spiral fluted spool high speed rotating in valve body, and the spiral fluted rotation direction is when spool rotates, spiral chute is pushed lubricant oil wherein to oil road, so the lubricant oil in the oil leab can flow fast and spray to timing sprocket from oil outlet, this has accelerated flowing of lubricant oil on the one hand, make the cooling effect of spool better, also help the lubricated of timing sprocket on the other hand; Relative motion surface can form the pressure oil film between spool and valve body simultaneously, makes spool and valve body be able to effectively lubricating, helps reducing the friction between spool and valve body.
Description of drawings
Now in conjunction with the accompanying drawings the utility model is described in further detail.
Fig. 1 looks generalized section for the master of a kind of concrete structure of rotary distribution device described in the utility model;
Fig. 2 is the cross-sectional schematic of spool in the distribution device.
Embodiment
As shown in Figure 1 and Figure 2, this rotary distribution device of quartastroke engine with screw lubrication oil duct comprises valve body 5 and is positioned at the cylindrical body rotary spool 4 of valve body 5, spool 4 one ends are equipped with timing sprocket 2, and spool 4 is parallel with bent axle and pass through this timing sprocket 2 by the bent axle driven rotary.On spool 4, offer the gas-entered passageway 11 and the exhaust passage 10 that can be communicated with the firing chamber, exhaust passage 10 is formed by the axial bore connection that is opened in the radial hole on the spool 4 and be opened on the spool 4, on spool 4 circumferential surfacies of 10 peripheries, exhaust passage, offer spiral chute 8, the two ends of spiral chute 8 are the circular groove 7 that is communicated with this spiral chute 8 respectively, 9, on valve body 5, offer oil input channel 6 and oil road 3, wherein a circular groove 7 is communicated with oil input channel 6, another circular groove 9 is communicated with oil road 3, to guarantee when spool 4 high speed rotating, oil input channel 6 and oil road 3 can remain with the good of spiral chute 8 and be communicated with, the rotation direction of spiral chute 8 should make when spool 4 rotations, spiral chute 8 pushes lubricant oil wherein to oil road 3, promptly from the left apparent direction of Fig. 1, if spool 4 rotation counterclockwise, the rotation direction of spiral chute 8 is left-handed.The oil outlet 1 of oil road 3 is opened in and is installed in adjacent valve body 5 end faces of timing sprocket 2 of spool 4 ends, makes from the lubricant oil of oil outlet 1 ejection to be ejected on the timing sprocket 2, with lubricated timing sprocket 2.
The filler opening of oil input channel 6 is connected with engine oil pump, and then the screw lubrication oil duct of being made up of oil input channel 6, spiral chute 8 and oil road 3 can effectively cool off and lubricate this rotary distribution device.
