Abstract

A power tool comprising: a housing, a motor assembly disposed in the housing, an output shaft at least partially received in and rotatable relative to the housing, and an impact assembly operatively coupled with the motor assembly and configured to be driven thereby, the impact assembly comprising: a hammer defining a hammer chamber therein for receiving a fluid therein and an inwardly protruding impact member, the hammer configured to be rotationally driven upon rotation of the motor assembly; an anvil defining an anvil chamber therein, the anvil at least partially disposed in the hammer chamber and configured to rotationally drive the output shaft; the anvil comprising a body portion configured to be rotatable relative to the hammer, and a reciprocating member configured to selectively move radially outwardly relative to the body portion to be impacted by the impact member of the hammer according to pressure of fluid in the anvil chamber so that the hammer imparts rotational movement to the body portion wherein the impact assembly is configured to operate in an environment having an ambient temperature range between -30°C and 50°C without stall of the impact assembly.
