ABSTRACT:
Apparatus and methods for fitting mechanical parts to minimize prevent free play are described. An apparatus having a piston is designed so as to restrain the piston before actuation, and so as to allow the piston to gain momentum before striking an object. The described apparatus are applicable to devices involving shearable elements. An embodiment of the invention relates to a pyrotechnically activated valve incorporating such features to minimize free play in conjunction with such features so as to restrain the piston and also allow the piston to gain momentum.
