Abstract: A rotary atomizer comprises an electric motor having a stator and a rotor, a vertical shaft, one or more porous gas bearings configured to provide frictionless radial and axial support to the shaft, and a rotating disc installed at a lower end of the shaft, said rotating disc configured to spray liquid into the form of fine particles. A gap detection system monitors a distance between the porous gas bearings and the vertical shaft. Bushings on the motor housing help to maintain precise alignment of the rotor during installation and maintenance.

Abstract: An improved rotary disc atomizer for use in, for example, spray dryers or congealers is disclosed. The rotary disc may be directly mounted to the shaft of a high-speed electrical motor. The high-speed electrical motor comprises a permanent magnet rotor and electro-magnetic bearings. The electro-magnetic bearings may be supported by one or more upper/lower bearing housings and used to enable frictionless support of the shaft/rotor and rotary disc. The atomizer system may further comprise a gas distributor enabled to dynamically adjust the velocity at which the gas leaves the radial vanes and meets with the atomized droplets.

Abstract: The rotary atomizer disk has an upper part and a lower part connectable to the upper part using a plurality of screws. The disk comprises a number of atomizer nozzle insert receiving holes for receiving a corresponding number of nozzle inserts from outside the disk, and a number of screw receiving bores passing at least partially through each of the insert receiving holes for receiving the screws connecting the lower part to the upper part. In this way, by removing any one of the screws, a corresponding one of the nozzle inserts can be removed from the disk without disassembling it. The inserts may be symmetrical and be turned or reversed to be reused. The invention avoids the need to rebalance the disk after disassembling for nozzle replacement purposes.

Abstract: An auxiliary suspension unit for mounting parallel to a standard shock absorber comprises a cylinder receiving a piston which includes a piston head mounted to a piston rod and defining in the cylinder first and second chambers filled with oil. The first chamber is on the rod side of the piston head. A spring structure comprises a floating piston and a high pressure accumulator contained in a third chamber with the floating piston being slidable therein. The working fluid from the second chamber exerts pressure on the floating piston and is opposed by the high-pressure accumulator of the third chamber. The auxiliary unit also comprises an actuator for positioning a valve provided on the piston into first and second positions thereof and further comprises a control device for the actuator. In the first position of the valve and upon compression of the auxiliary unit, a bypass allows fluid transfer from the second to the first chamber.
