Abstract

DC60 in the system to operate the engine valve. The timing chamber (48) is formed on one side of the engine main body. Which the timing transmission room (48) will contain The timing transmission (37) provided a section for the connection between the crankshaft (12) and the shaft. The supported cam (36) is on the cylinder head above the intake and exhaust valves (29i, 29e). The opposite end of the camshaft (36) is supported by the side wall (5a). One side of the lid Cylinder (5) and walls for partitioning (5b) To be placed next to the timing room (48) and the The action of the camshaft sealing valve (49) (36) is bounded between one side wall (5a) and the partition wall (5b). The lubricant crankcase piece (72) is arranged. Placed in At the bottom of the timing chamber (48), the lubricant holes (75) are arranged. It is prepared in a partition wall (5b) where the lubricant path hole (75) controls the resulting lubricant. Receive a splash through a shake-off in the upper part of the timing transmission (37) to the valve operating chamber (49). The lubricant return path (77) is provided just in case. Through a pulsating ripple pressure that has been induced in the crankcase (9) to the chamber for It works of the valve (49) and causes the lubricant that has been accumulated in the working valve chamber (49) to flow downwards to the crankcase (9) inside the crankcase (2). room The timing and operating chamber of the valves which are separated can be Lubricated without preparing a lubricant bath At the same time, it still maintains the condition Place where the camshafts are positioned above the intake and exhaust valves. In the system to operate the engine valve The timing chamber (48) is formed on one side of the engine main body. Which the transmission room (48) will cover the system The transmission timing (37) provided for the connection between the crankshaft (12) and the camshaft (36) is supported on the cylinder head above the intake and exhaust valves (29i, 29e), the opposite end of the camshaft (36) is supported by a side wall (5a), one side of the cylinder head (5) and a partition wall. (5b) to be adjacent to the timing chamber (48) and the valve operating chamber (49), camshaft cover (36) to be positioned between the side wall (5a). One and a partition wall (5b). The lubricant chain (72) is placed in the lower section. Of the timing chamber (48), a hole that is the lubricant path (75) is provided in Partition wall (5b) in which the lubricant path hole (75) controls the treated lubricant. The fluttering splash throws over the upper portion of the timing transmission (37) to the chamber to Valve operation (49), return oil path (77) will be provided. It transmits the induced pressure stroke in the crankcase (9) to the valve operating chamber (49) and allows the accumulated lubricant in the valve chamber (49) to flow. Downward to the crankcase (9) located inside the crankshaft (2), so the internal part of the transmission The timing power and the operating chamber of the valves which have been separated can be cast. Glides on without the provision of a lubricant bath. At the same time, it still maintains its layout. Where the camshafts are positioned over the intake and exhaust valves.

Claims (4)

1. Engine valve operation system where the timing transmission chamber (48) is formed on one side of the engine main body (1), formed from the crankcase chamber. The crankcase (2), the cylinder block (3) and the cylinder head (5), the timing transmission chamber (48), cover the transmission (37), which provides a connection between the crankshaft (12). It is supported on the crankshaft chamber (2) and the camshaft (36) supported on the cylinder head (5) above the intake and exhaust valves. Failure (29i, 29e), the opposite end of the camshaft (36), is supported by a side wall (5a), one side of the cylinder head (5) and a dashed partition wall (5b). Formed in the cylinder head (5) so that it is adjacent to the timing chamber (48) and the valve operating chamber (49). The cam (36) will be assigned between one side wall (5a) and the partition wall (5b), which has been characterized by that the lubricant link (72) will be arranged. Placed In the timing chamber (48), where the lubricant chain (72) splashes the lubricant (71) that has been deposited in the base of the timing chamber (48) to store the lubricant (71) on top. part On the underside of the timing transmission (37), holes that form the lubricant path (75) are provided. In the partition wall (5b), the lubricant path hole (75) controls the lubricant that A fluttering splash has been given to the upper portion of the timing transmission (37) to the valve operating chamber (49) and a return oil return path (77) is provided. It is placed in the cylinder head (5) and the cylinder block (3) where the return path of the lubricant (77) passes through the stroke. The pressure has been induced in the crankcase (9) inside the crankshaft chamber (2) to the chamber for Operates the valve (49) and causes the lubricant that has been accumulated in the valve working chamber (49) to flow downward to the crankcase (9). 2. A system for engine valve operation in accordance with claim No. 1, which has been characterized by that The access door (55) opens the other side face of the cylinder head (5), where the access port (55) can enable the rotatable driven assembly (46) of the transmission. Timing (37) has been assembled, attached and disassembled from The camshaft (36), the side wall of the body, the cover (57), that covers the access hatch (55), is tilted relative to the lateral surface of the rotated driven assembly. Yes (46) in such a way that the splashed lubricant, which has been flicked in the The top of the transmission, timing (37) is bounced back on the interior surface of the side wall of the The lid body (57) to move to the sides of the rotatable driven assembly (46) and through holes (64) that allow the splashed lubricant to pass through. Pre-assembled in rotatable drive assembly (46). 3. The system for engine valve operation in accordance with claim 2, which is characterized by that the lubricant path channel (76) is provided in the partition wall. (5b) where the lubricant path channel (76) provides a contact between the timing chamber (48) and the operating chamber of the valve (49) and the bearing surrounding (41) of Camshaft (36) 4.A system for the operation of the engine valve corresponding to any of the 1st to 3rd claim. Which has been made with that special feature A one-way valve (79) will be supplied. In the hole in the lubricant path (75), where the one-way valve (79) helps to increase the It is only suction that is passed from the valve operating chamber (49) to the timing chamber (48).
