Hydraulic module with 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 module with a switch valve for controlling a flow of a hydraulic fluid in a connecting rod for an internal combustion engine with variable compression with an eccentrical element adjustment arrangement for adjusting an effective connecting rod length,

• wherein the eccentrical element adjustment arrangement includes a first cylinder and a second cylinder configured as hydraulic chambers,
• wherein a first inlet is provided for feeding the hydraulic fluid into the first cylinder and a second inlet is provided for feeding the hydraulic fluid into the second cylinder,
• wherein a first outlet is provided for draining the hydraulic fluid from the first cylinders and a second outlet is provided for draining the hydraulic fluid form the second cylinder,
• 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 is arranged in the first inlet and facilitates feeding the hydraulic fluid into the first cylinder and prevents draining the hydraulic fluid from the first cylinder,
• wherein the second check valve is arranged in the second inlet and facilitates feeding the hydraulic fluid into the second cylinder and prevents draining the hydraulic fluid from the second cylinder,
• wherein the switch valve includes a piston which is displaceable into a first switching position or a second switching position, and
• wherein the first cylinder and the second cylinder are connected so that hydraulic fluid is conductible in the first switching position from the first cylinder into the second cylinder,
• wherein a supply conduit of the switch valve includes a second aperture configured as a second throttle through which the hydraulic fluid can drain in a throttled manner and is suction feedable in a throttled manner in the first switching position and
• wherein a third check valve is provided in the supply conduit parallel to the second aperture wherein the third check valve facilitates feeding hydraulic fluid into the switch valve and prevents an outflow of the hydraulic fluid.
