Hydraulic arrangement with a switch valve for controlling a hydraulic fluid flow of a connecting rod for an internal combustion engine with variable compression and connecting rod

A hydraulic arrangement, comprising:

• a switch valve configured to control a hydraulic fluid flow of a connecting rod of an internal combustion engine with variable compression including an eccentrical element adjustment device for adjusting an effective connecting rod length,
• wherein the eccentrical element adjustment device includes at least a first cylinder and a second cylinder forming hydraulic chambers,
• wherein a first inlet is provided for feeding hydraulic fluid into the first cylinder through a supply conduit,
• wherein a second inlet is provided for feeding hydraulic fluid into the second cylinder through the supply conduit,
• wherein a first outlet is provided for draining hydraulic fluid from the first cylinder,
• wherein a second outlet is provided for draining hydraulic fluid from the second cylinder,
• wherein the switch valve includes a displaceable piston which is displaceable into a first switching position or a second switching position,
• wherein the first outlet of the first cylinder is connected with the supply conduit in the first switching position and the second outlet of the second cylinder is connected with the supply conduit in the second switching position,
• wherein a first check valve is associated with the first cylinder and a second check valve is associated with the second cylinder,
• wherein the first check valve facilitates feeding hydraulic fluid into the first cylinder and prevents draining hydraulic fluid from the first cylinder,
• wherein the second check valve facilitates feeding hydraulic fluid into the second cylinder and prevents draining hydraulic fluid from the second cylinder,
• wherein the first cylinder and the second cylinder are connected so that hydraulic fluid is transferable from the first cylinder into the second cylinder in the first switching position.
