Abstract
A linear actuator for a high-pressure pump (1), the actuator comprising a rolling spindle with a shaft (10), a first nut (21) and a second nut (22), the nuts (21, 22) operatively connected to a first threaded section (11) and a second threaded section (12) of the shaft (10), respectively, the sections being configured with opposite threading directions, such that when rotating the nuts (21, 22) in opposite directions, the shaft (10) is axially movable with respect to the nuts (21, 22) in one same direction and an actuator for driving the movement of the shaft (10) simultaneously rotating the nuts (21, 22) in opposite directions.

A linear actuator for a high-pressure pump (1), comprising a rolling screw with a shaft (10), a first nut (21) and a second nut (22), the nuts (21, 22) being operatively connected to a first threaded section (11) and a second threaded section (12) of the shaft (10), respectively, configured with opposite threading directions, such that when rotating the nuts (21, 22) in opposite directions, the shaft (10) can be axially displaced with respect to the nuts (21, 22) in one and the same direction, and a drive for driving the displacement of the shaft (10), simultaneously rotating the nuts (21, 22) in opposite directions.
