Description
本發明有關一種引擎閥門可變揚程的油控閥構造，尤指可避免油控閥對其他部品的的維修產生干擾，及可縮短油控閥與該油控驅動機構之間的控制油路，俾能令油壓力之耗損減少，同時可使該油控閥控制與驅動該油控驅動機構更能精確化之構造。The invention relates to a fuel control valve structure with a variable head of an engine valve, in particular to avoid interference of the oil control valve to the maintenance of other parts, and to shorten the control oil path between the oil control valve and the oil control drive mechanism,俾 can reduce the loss of oil pressure, and at the same time enable the oil control valve to control and drive the oil control drive mechanism to be more precise.
按，習知之引擎1之可變氣門揚程機構油路配置構造，請參閱圖一所示，係將一電磁閥2設置於汽缸頭11之上方，而該油壓入口之潤滑油係藉由油管21係將其外部之油壓直接導入電磁閥2中，再由電磁閥2將潤滑油導入汽缸頭11內之油路，以油壓推動各汽缸之可變揚程機構，以因應引擎1之高低速運轉時不同揚程之進、排氣閥門切換。According to the conventional valve head oil passage arrangement structure of the engine 1, as shown in FIG. 1, a solenoid valve 2 is disposed above the cylinder head 11, and the oil pressure of the oil pressure inlet is by the oil pipe. The 21 series directly introduces the external hydraulic pressure into the solenoid valve 2, and then the lubricating oil is introduced into the oil passage in the cylinder head 11 by the electromagnetic valve 2, and the variable lift mechanism of each cylinder is pushed by the hydraulic pressure to cope with the high speed of the engine 1. In the low speed operation, the inlet and exhaust valves of different lifts are switched.
習知之引擎1藉由該電磁閥2及油管21之設置，雖然可以達到配合引擎1高低速運轉時不同揚程之進、排氣閥門切換，然而，由於電磁閥2係以複數個螺絲22鎖付於汽缸頭11上，因此於組裝時較為繁複，而該電磁閥2所外接之油管21，因有洩油之虞慮，且其係外露於引擎1之外，故容易因引擎1高溫而產生脆化及損壞，此外，由於該電磁閥2係設置於汽缸頭11上方，因此容易導致該引擎1於擺動時，該電磁閥2容易與上方之部品如置物箱等產生干涉。The conventional engine 1 is configured by the solenoid valve 2 and the oil pipe 21, and can be switched to the inlet and exhaust valves of different lifts when the engine 1 is operated at a high speed and a low speed. However, since the solenoid valve 2 is locked by a plurality of screws 22 The cylinder head 11 is complicated in assembly, and the oil pipe 21 externally connected to the electromagnetic valve 2 is exposed to the engine 1 due to oil leakage, so it is easy to be generated due to the high temperature of the engine 1. The electromagnetic valve 2 is disposed above the cylinder head 11 and is likely to cause the electromagnetic valve 2 to easily interfere with an upper part such as a storage box or the like when the engine 1 is swung.
有鑒於習知之可變揚程機構油路配置構造具有上述之缺失，是以，要如何提供一種可簡化引擎之組裝及方便配置潤滑油路之油控閥，以及可使機油泵小型化與減少引擎動力的損失之結構，實為目前機車製造業者所亟待克服之課題。In view of the above-mentioned lack of the variable head mechanism oil circuit configuration, it is necessary to provide an oil control valve that simplifies the assembly of the engine and facilitates the arrangement of the lubricating oil circuit, and can miniaturize and reduce the engine of the oil pump.

本發明之功效在於，藉由於汽缸頭33的進氣埠331側之面上設置油控閥安裝座334，該油控閥安裝座334可供油控閥4設置，該油控閥4係朝曲軸箱31方向延伸，該油控閥安裝座334的插接座部3342與汽缸頭33之間保持有間距，該間距可形成一通道，而通道可使冷卻風扇311吸入的冷卻風流通，藉此該冷卻風不會因為該油控閥安裝座334及油控閥4的設置而產生阻礙，造成降低汽缸頭33之冷卻效果；同時可令油控閥4能遠離引擎3之高溫處，且可避免油控閥安裝座334形成一聚熱體，進而來增進油控閥4之耐用性，以及可達到該油控閥4容易配置與避免油控閥4對其他部品維修產生干擾之功效；另藉此可縮短油控閥4與該油控驅動機構354之間的控制油路41，俾能令油壓力之耗損減少，同時可使該油控閥4控制與驅動該油控驅動機構354更能精確化。The effect of the present invention is that the oil control valve mount 334 is provided for the oil control valve 4 by the oil control valve mount 334 provided on the side of the intake manifold 331 side of the cylinder head 33, and the oil control valve 4 is directed toward The crankcase 31 extends in the direction of the gap between the socket portion 3342 of the oil control valve mounting seat 334 and the cylinder head 33. The spacing can form a passage, and the passage can circulate the cooling air sucked by the cooling fan 311. The cooling air is not hindered by the arrangement of the oil control valve mount 334 and the oil control valve 4, thereby reducing the cooling effect of the cylinder head 33; at the same time, the oil control valve 4 can be kept away from the high temperature of the engine 3, and The oil control valve mount 334 can be prevented from forming a heat collecting body, thereby improving the durability of the oil control valve 4, and the effect that the oil control valve 4 can be easily configured and the oil control valve 4 can be prevented from interfering with other parts maintenance; In addition, the control oil path 41 between the oil control valve 4 and the oil control driving mechanism 354 can be shortened, so that the oil pressure loss can be reduced, and the oil control valve 4 can be controlled and driven to drive the oil control driving mechanism 354. More accurate.
綜上所述，本發明藉由上述之配置構造，確實能改善習用之缺失，而能達成所訴求之目的與功效，應已符合發明專利所述之實用性、新穎性，以及進步性之要件，爰依法提出發明專利之申請，祈請 貴審查員之詳鑑，惠賜准予發明專利之審定，至感德便。In summary, the present invention, by the above configuration, can indeed improve the lack of conventional use, and can achieve the purpose and effect of the claim, and should have met the practicality, novelty, and progressive requirements described in the invention patent.爰Proposing an application for a patent for invention in accordance with the law, and asking for the detailed examination of your examiner, and granting the approval of the invention patent to the sensibility.
