Abstract
A fluid driven tool has an outer housing and an inner motor housing nested in the outer housing and defining a cavity therebetween that has a first end with a first exhaust passageway and a second end with a second exhaust passageway. The inner motor housing has a motor chamber with an inlet port for a fluid driven motor and fluid inlet, and an inlet manifold disposed in the cavity. The inlet manifold has a recessed portion with a surrounding seal that engages the inner motor housing and connects the fluid inlet to the at least one inlet port of the inner motor housing. An inner surface of the outer housing and an outer surface of the inner motor housing have portions that mate upon nesting the inner motor housing in the outer housing and provide reinforced areas for clamping regions of the outer housing located over the reinforced areas.
