  • Damper for a high pressure chamber of a variable valve train module
    Patent number: 10415436
    Abstract: A variable valve train module selectively controls the opening and closing of a valve of an engine. The variable valve train module includes a drive element configured to be driven by a cam which rotates on a camshaft, a pump which is driven by the drive element, and a hydraulic control unit. The hydraulic control unit is configured to control the engine valve. The hydraulic control unit has a high pressure chamber containing hydraulic fluid which is selectively pressurized by the pump. The hydraulic control unit also has a control valve which is configured to depressurize the high pressure chamber, and a damper which is configured to increase an effective volume of the high pressure chamber when a pressure in the high pressure chamber exceeds a threshold value.
