FIELD: power engineering; petrochemical and gas industries. SUBSTANCE: wave pressure exchanger includes housing with gas distributors secured on it, bearing seats fitted in gas distributors and rotor mounted at axial clearances relative to gas distributors. Shafts of rotor is mounted in bearings. Bearings are located on one side of rotor; they are fitted in bush mounted on shaft by means of threaded joint; bush has bead on side of rotor and pressure nut on opposite side. Bush, hold-down and pressure nuts are made for fixing axial positions relative to shaft, bush and gas distributors. EFFECT: enhanced operational reliability due to ease of control and adjustment of end clearances between rotor and gas distributors. 1 dwg
