OIL REGULATOR IN ALL-MODE VALVE MANIFOLD SYSTEM OF INTERNAL COMBUSTION ENGINE Russian patent published in 2018 - IPC F01L1/344 F01L9/02 

FIELD: engine devices and pumps.

SUBSTANCE: oil regulator in the all-mode valve manifold system of the internal combustion engine is connected to the valve system of internal combustion engine control valve, consisting of a casing (1), a spool valve, a hydraulic accumulator, and a transmission mechanism. The spool valve, hydraulic accumulator and transmission mechanism are installed in the casing (1). The spool valve consists of a spool pin (3) and a valve bush (2). The spool pin (3) is installed in the valve bush (2) with the teeth (2-1) at one end. The valve bush (2) is installed in the casing cavity (1). On the casing (1), the rack is provided in a position corresponding to the teeth (2-1) of valve bush (2). The comb (2-2) of rack is engaged with the teeth (2-1) on valve bush (2). The hydraulic accumulator installed in the casing cavity (1) consists of an accumulator piston (4-1), a spring (4-2) of the accumulator piston, an end cover (4-4), a socket O-ring (4-6), and a rubber ring (4 -5). The socket O-ring (4-6) and the rubber ring (4-5) are fixed in the housing cavity. The hydraulic accumulator piston is resiliently installed in the cavity of the casing (1). The end cover (4-4) is fixedly mounted on the end surface of the casing (1). The spring (4-2) of the hydraulic accumulator piston, which is a pressure spring, is installed between the piston (4-1) of the hydraulic accumulator and the end cover (4-4). Between the spoon valve and the hydraulic accumulator there is a battery case. The transmission mechanism consists of a gear train (5-1), a shaft (5-2) of the gear train, and a cross disc coupling (5-4). The gear train (5-1) is mounted on the shaft (5-2) of the gear train by means of a keyed connection (5-3). The shaft (5-2) of the gear train is connected to the spoon core (3) by means of a cross disc coupling (5-4).

EFFECT: increasing stability and reliability of work.
