The invention relates to a linear actuator having a double pump (23, 24) and a differential cylinder (9), the annular chamber (48) or piston rod chamber of which is delimited by an annular surface (A1) or piston rod surface of a piston and is connected to a first pump (23), and the piston bottom chamber (50) of which is delimited by a piston bottom surface (A2) of the piston and is connected to a second pump (24). Both pumps are driven by a common variable-speed electric motor (26). The ratio of the annular surface area to the piston bottom surface area is equal to the ratio of the delivery volume of the first pump to the delivery volume of the second pump. According to a first variant, this is achieved by adjusting the rotational speeds of the two pumps by means of a gear unit (26). According to a second variant, this is achieved by designing a pump having an adjustable delivery volume. According to a third variant this is achieved in that, at a constant pump speed, the ratio of the displacement volumes of the pumps corresponds to the ratio of the cylinder surface areas.
