Abstract (en)
[origin: EP1602826A1] The drive has a rotary-to-linear conversion mechanism to convert rotary into translation movement. The mechanism has a rotary unit and a piston unit (7) that is intended to move a piston of a pump. A stepping motor (2) engages the piston unit to drive it in a linear reciprocating movement. The motor and the mechanism drive the rotary unit in a reciprocating angular movement at an angle of less than 360 degrees. An independent claim is also included for a method of controlling a pump drive.
