Abstract
An actuator assembly for generating a fluid pressure and applying the fluid pressure to a first device. The actuator assembly comprises a first fluid chamber and a first piston disposed adjacent to the first fluid chamber, a second fluid chamber and a second piston slidably received in the second fluid chamber, a fluid passage connecting the first fluid chamber with the second fluid chamber, and an actuator motor for selectively reciprocating the first piston so that axial movement of the first piston generates a fluid pressure within the first fluid chamber. The first piston is disposed within the actuator motor. As the first chamber is fluidly communicating with the second fluid chamber, the linear motion of the first piston causes corresponding linear motion of the second piston for applying the fluid pressure to the first device.
