ABSTRACT:
A control valve assembly for a pneumatic paving breaker which enables the maximum amount of energy to be imparted to the piston on its working stoke while restricting the energy imparted to the piston on its return stroke and which utilizes a reduced consumption of air, has an optimum speed of response and is relatively cheap to manufacture. This is achieved by having a valve member in the form of a pure cylindrical slug which reciprocates in a valve block in which it is a clearance fit.
