1. A handheld impact driver comprising:
an air supply port configured for connection to an external source of pressurized air; a manifold assembly positioned downstream of the air supply port, the manifold assembly comprising a manifold, the manifold defining a manifold inlet port, the manifold inlet port being in selective fluid communication with the air supply port; and a pressure regulator positioned downstream of the manifold assembly, the pressure regulator comprising a housing and a diaphragm assembly movably coupled with the housing, the housing and the diaphragm assembly cooperating to define a discharge chamber, the housing at least partially defining an inlet chamber, the inlet chamber and the discharge chamber being in at least intermittent fluid communication; wherein: when the manifold assembly is in a first configuration, the manifold inlet port is in fluid communication with the inlet chamber defined by the pressure regulator to permit the flow of pressurized air to the inlet chamber, the pressure regulator being operable to regulate the pressurized air and discharge regulated, pressurized air at a substantially constant, predetermined pressure; and when the manifold assembly is in a second configuration, the pressure regulator is bypassed. |
