Abstract
An apparatus that controls impact noise of a solenoid by energy dissipation through both resilient and pneumatic devices. This is achieved by providing a device between the plunger of the solenoid and a machine member. The device includes a predetermined number of orifices which are of different sizes and placed at different locations. This forms an air metering system and controls the stiffness of the device for maximum impact noise attenuation.
