Abstract
A rotary, regenerative heat exchanger includes an inner cylindrical hub (2) provided in a vertical position, a rotor (1) containing a heat exchange medium, first attachment members (30) for attaching the rotor to the hub, and a stationary casing (6) surrounding the rotor. A bearing (3) is provided to journal a lower end of the hub, and a slow moving hydraulic motor (4) is adapted to slowly turn the hub. The motor is provided with a housing enclosing a built-in radial bearing (26) and coaxially therewith a cylinder block and cam surface arrangement having a circular cylinder block (24) and a cam surface (21) surrounding the cylinder block and cooperating with a piston mechanism (22, 23) of the cylinder block such that reciprocation of the piston mechanism causes relative motion between the cylinder block and the cam surface. Second attachment members (5, 8, and 10) are provided to attach the motor to the stationary casing and to the hub, respectively. And an upper bearing of the hub consists only of a combination of the built-in radial bearing of the motor and the cylinder block and cam surface arrangement.
