Abstract (en)
[origin: EP0461943A2] The gas compression device comprises a motor (1), a piston (2) capable of moving linearly in a pump body, a means of transmission (T) between the motor (1) and the piston (2) capable of converting the rotary movement supplied by the motor (1) into a reciprocating translational movement of the piston (2). Means of varying the speed, comprising a cam (12) are provided for imparting a different speed to the piston (2) of the compressor according to the resistance offered to the motor (1) during a complete admission-compression cycle, in such a way that the load moment is essentially constant and the motor (1) functions at its maximum torque and therefore at its maximum efficiency. The profile of the cam (12) is determined so as to ensure an essentially isothermic compression of the gas. <IMAGE>
