THROTTLE FLOW DIVIDER Russian patent published in 2023 - IPC F15B13/02 G05D7/00 G05D7/01 F15B13/06 

FIELD: hydraulic engineering.

SUBSTANCE: invention can be used in hydraulic drives of the operating elements of agricultural, road-building, mining machines and mechanisms, as well as in the automation of various technological and production processes. A throttle flow divider is proposed, containing a housing 1 with inlet 2 and output 10, 11 channels, in which a membrane 7 is installed, dividing the housing 1 into two chambers 5, 6, connected to the inlet channel 2 of the housing through constant resistances 3, 4 and with output channels 10, 11 through holes in the form of slots 8, 9, which form regulatory organs with the membrane. The slots 8, 9 are made in inclined walls and the width of the slots decreases from the maximum at the upper point to the minimum at the lower point, the elastic membrane 7 has a variable thickness, whereas at small adjustable pressure drops, the gap covering with an elastic membrane starts from its greater width, and at large differences in adjustable pressures, the gap is covered with an elastic membrane, it starts at its smaller width.

EFFECT: increased accuracy of flow division.
