: Many motors include a third, smaller "drain" line (indicated by a dotted or dashed line in schematics) to carry internal leakage back to the tank, preventing pressure buildup that could damage shaft seals.
: Returns fluid from the motor's outlet back to the reservoir (tank). shema vkljuchenija gidromotora
: Carries high-pressure fluid from the pump to the motor's inlet. : Many motors include a third, smaller "drain"
: Controls the flow direction to rotate the motor forward, reverse, or stop it. Hydraulic circuit diagrams (hydraulic schematics) : Many motors include a third
