A wave energy converter comprising an upright standard anchored to the bottom of a body of water. A vertical sleeve is supported for rotation on and relative to the standard about a common vertical axis. The sleeve contains at its upper end a double-acting pneumatic pumping chamber containing a vertically slidable piston and a piston rod that extends sealingly through a lower end of the pumping chamber. A generally horizontally extending arm is pivotally connected to the lower end of the piston rod and pivotally supported on the sleeve intermediate the length of the arm about a pivot fixed relative to the sleeve. A float is connected to the end of the arm remote from the sleeve. Conduits receive air expelled alternately through opposite ends of the pumping chamber and convey the air away from the converter. A swivel joint is disposed in one of the conduits for permitting rotation of an upstream portion of the conduit relative to a fixed downstream portion of the conduit.
