A mechanical device for generating actuating movement has a housing defining a first bore and a second bore contiguous therewith. The housing also defines radial ports that allow an environment about the housing to communicate with the first bore. A first piston is slidably mounted in the first bore. A second piston is slidably mounted in the second bore and is positioned so that it is flush with the first bore. A spring, coupled to the first piston, is capable of an at rest state in which the first piston seals off the radial ports while being spaced apart from the second piston. The spring is also capable of a compressed state in which the first piston is positioned such that the radial ports communicate with the first bore between the first and second pistons. When the spring is released from its compressed state and allowed to transition to its at rest state, the first piston moves to seal off the radial port(s) and subsequently pressurize any fluid in the first bore between the first piston and the second piston. If the fluid is incompressible (e.g., water), the pressurized fluid drives the second piston along the second bore to create the actuating movement.
