Abstract
A vibration dampening system for a reciprocating compressor with a linear motor of the type comprising a motor-compressor assembly having a reference assembly ( ) formed by a motor and a cylinder ( ) and mounted inside a shell ( ) and a resonant assembly ( ) formed by a resonant spring ( ) and piston ( ) reciprocating inside the cylinder ( ), the system comprising at least one first balancing means ( ) connecting the reference assembly ( ) to the shell ( ), and at least one second balancing means ( ) connecting the resonant assembly ( ) to the shell ( ), both balancing means ( ) actuating according to the displacement direction of the piston ( ), said second balancing means ( ) presenting a coefficient of elasticity proportional to the coefficient of elasticity of the first balancing means ( ) by a factor defined by the ratio of the masses of the resonant assembly ( ) and of the reference assembly ( ), respectively.
