Abstract
A hydraulic hammer for a machine is provided. The hydraulic hammer includes a housing and a piston disposed within the housing and adapted to reciprocate along a longitudinal axis of the housing. The hydraulic hammer further includes a first chamber and a second chamber defined within the housing. The hydraulic hammer further includes a primary passage extending from an inlet and branching into a first passage and a second passage. The first passage fluidly communicates the primary passage with the first chamber and the second passage fluidly communicates the primary passage with the second chamber. The hydraulic hammer further includes a flow control device coupled to the first passage. The flow control device includes a valve element adapted to move between a first position and a second position based on an input signal indicative of a pressure of charge in the first chamber.
