Abstract

The present invention relates to a hydraulic breaker (10). The hydraulic breaker (10) comprises a casing (12) and a power cell (14) supported within the casing. The casing (2) and power cell (14) mechanically engage with each other such that the power cell is compressed. The hydraulic breaker (10) is configured such that there is no part between an outside surface of a lower housing of the power cell (14) and an inside surface of the casing adjacent the lower housing (12).
