Abstract
A turbomachine comprising a thrust air bearing for axially supporting the rotary shaft of the turbomachine. The thrust air bearing comprises a disc shaped hollow runner fixed onto the rotary shaft, and a pair of stationary bearing plates fixed onto the housing of a turbocharger on each side of the runner. The runner has a thin wall defining an interior chamber therein. A plurality of air inflow bores is formed on the side wall of the runner for feeding ambient air into the interior chamber, and a plurality of air outflow bores is formed on the circumferential outer wall of the runner for discharging the air within the interior chamber into the atmosphere.
