Abstract
A speedup device for reciprocating cylinders which make use of fluid pressure such as hydraulic pressure or pneumatic pressure. The speedup device incorporates a poppet valve adapted to be moved for valving upon application of fluid pressure and is installed in a pipe line connecting a control valve to the front and rear chambers of a cylinder, the arrangement being such that when the rod of the reciprocating cylinder is to be extended, all the return from the front cylinder chamber flows into the rear chamber, thereby speeding up the extension of the rod of the reciprocating cylinder.
