HYDRAULIC HEIGHT ADJUSTMENT DEVICE OF A MOTOR VEHICLE AND MOTOR VEHICLE

A hydraulic height adjustment device of a motor vehicle includes at least one hydraulic pump arrangement connected via feed branch to at least two actuators for adjusting a vehicle level. A hydraulic fluid may be pumped from a tank arrangement into at least one of the at least two actuators. A switching valve may be connected upstream of the actuators to permit or prevent an inflow or outflow of hydraulic fluid. The at least two actuators may be connected via a return branch to the at least one tank arrangement. A pilot pressure-controlled return valve may be configured to hold the return branch open below a defined switching pilot pressure, and the return valve may hold the return branch closed at or above the switching pilot pressure. A pilot pressure line, via which a pilot pressure can be supplied, may be provided between the pump arrangement and the return valve.
