Abstract
The invention relates to a novel lubricating oil circuit for a valve mechanism of a diesel engine. The lubricating oil circuit is realized through a machine body, an outer oil pipe, a camshaft supporting body and an oil circuit inside an air cylinder cover, wherein the lubricating oil circuit is provided with a machine body main oil passage (1), the machine body main oil passage (1) is connected with an external oil pipe connecting port (2) through the oil circuit, the external oil pipe connecting port (2) is connected with an oil inlet hole (3) of the camshaft supporting body through the external oil pipe, the oil inlet hole (3) of the camshaft supporting body is communicated with a main oil passage (4) of the camshaft supporting body, the main oil passage (4) of the camshaft supporting body is connected with a camshaft hole oil passage (5) and an exhaust rocker arm oil passage (7), the camshaft hole oil passage (5) is connected with an intake rocker arm shaft hole oil passage (6), and an oil return passage (8) is connected with a crankshaft box through the air cylinder cover and the machine body. The lubricating oil circuits of the single jacking camshaft, an intake rocker arm and an exhaust rocker arm are integrated in the structural design of the camshaft supporting body, so that the structure of the diesel engine lubricating oil circuit is simplified.
