1. A hydraulic hammer of a machine, the hydraulic hammer comprising:
a housing; a piston disposed within the housing and adapted to reciprocate along a longitudinal axis of the housing; a first chamber defined within the housing; a second chamber defined within the housing; a primary passage extending from an inlet and branching into a first passage and a second passage, the first passage fluidly communicating the primary passage with the first chamber and the second passage fluidly communicating the primary passage with the second chamber; and a flow control device coupled to the first passage, the flow control device including 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, wherein the valve element allows flow of charge from the primary passage to the first chamber in the first position and restricts flow of charge from the primary passage to the first chamber in the second position, allowing the first chamber to be pressurized to a first pressure equal to the input signal and the second chamber to be pressurized to a second pressure greater than the first pressure through the inlet. |
