The rotation batch (-type) oil supply mechanism that the utility model provides can be used for diesel engine. As shown in Figure 1, tumbler 1Be connected to the air inlet and exhaust valve of diesel engine by valve bridging, tumbler is provided with batch (-type) oil supply mechanism.

For ease of explanation, Fig. 2 and Fig. 3 have provided the partial structurtes schematic diagram of batch (-type) oil supply mechanism, omitted intoThe dependency structures such as air bleeding valve. In the cylinder head of diesel engine, be provided with rocker arm bracket, rotating shaft 2 is arranged on rocker arm bracket, andAnd do not move along with the motion of tumbler 1. Between tumbler 1 and rotating shaft 2, be provided with lining 3, and lining3 modes by cold cover are closely connected with tumbler 1, in the time that tumbler 1 phase countershaft 2 rotates, follow togetherRotate.

Tumbler 1 be provided with the first oil supply gallery 4 and the second oil supply gallery 5, the first oil supply galleries 4 to push rod, veryPost fuel feeding, the second oil supply gallery 5 is to structure fuel feeding such as valve bridges. In the time of connection of rotating part 1 and lining 3, ensure theOne oil supply gallery 4 communicates with the second through hole 7 separately with the first through hole 6, the second oil supply gallery 5.

Rotating shaft 2 is provided with the first oil road 6, the second oil road 7 and oil input channel 10, and they are interior common in rotating shaft 2Form a pressure chamber.

Angle between the first oil road 8 and the second oil road 9 is 112 degree.

Explain the operation principle of this rotation batch (-type) oil supply mechanism below.

Feed lubricating oil from oil input channel 10 pressurizations. When air inlet and exhaust valve is closed, tumbler 1 drives by linkageMove to position shown in Fig. 2. Lining 3 is motion together thereupon, thereby the first oil supply gallery 4 and the first through hole 6,The relative position of the second oil supply gallery 5 and the second through hole 7 does not change. But the first oil road 8, second goes outOil duct 9 staggers with the first through hole 6, the second through hole 7 respectively, and the first oil road 8 and the second oil road 9 are all served as a contrastCover 3 sealings, thus lubricating oil is only closed in the pressure chamber in rotating shaft 2, keeps lubricating oil oil pressure; Even lubricatedOil oil pressure is larger, has a small amount of leakage, also can obtain well because of the throttling action in gap between rotating shaft 2 and lining 3Control.

Air inlet and exhaust valve by close transfer to open time, tumbler 1 is driven and is moved to gradually as Fig. 3 by linkageShown in position. Lining 3 is motion together thereupon, thereby the first oil supply gallery 4 and the first through hole 6, the second fuel feeding lead toThe relative position of road 5 and the second through hole 7 does not change. Now, 9 points of the first oil road 8, the second oil roadsDo not become from the state mutually staggering the state being interconnected with the first through hole 6, the second through hole 7, thereby first goes outOil duct 8, the second oil road 9 respectively with the first oil supply gallery 4, the second oil supply gallery 5 by the state mutually staggeringBecome the state being interconnected. The lubricating oil pressurizeing flows into the first oil supply gallery 4 and the second oil supply gallery 5, andFlow to and need lubricated position.

Air inlet and exhaust valve is transferred to while closing by opening once again, and tumbler 1 is driven gradually and moved to by linkagePosition as shown in Figure 2, lining 3 is motion and seal gradually the first oil road 8 and the second oil road 9 together thereupon,Thereby along with the duty demand of frame for movement quantitatively, supplying lubricating oil off and on, both met the profit of keypoint partSliding needs, can save again lubricating oil, reduce costs and reduce environmental pollution.

More than describe preferred embodiment of the present utility model in detail. Should be appreciated that the ordinary skill of this areaPersonnel just can make many modifications and variations according to design of the present utility model without creative work. Therefore, allIn the art technical staff according to design of the present utility model on the basis of existing technology by logic analysis, push awayReason or the limited available technical scheme of experiment, all should be by the determined protection domain of claimsIn.
