Abstract A liquid atomizing device comprises a cylindrical body provided with an inner cylinder having a cylindrical inner peripheral surface and an outer cylinder secured to the front end of said inner cylinder and having a cylindrical inner peripheral surface concentric with the inner peripheral surface of the inner cylinder. The inner peripheral surface of the outer cylinder has a larger diameter than that of the inner cylinder. The device includes a nozzle injecting a liquid against the inner peripheral surface of the inner cylinder during rotation of both of said cylinders at a high speed. The injected liquid is centrifugally scattered in a thin layer on the inner peripheral surface of the inner cylinder and spouted from its front end against the inner peripheral surface of the outer cylinder in a spray of fine particles, and further spouted from the front edge of the entire periphery of the inner peripheral surface of the outer cylinder in a spray of still finer particles due to the larger centrifugal force thereof exerted by the rotation of the outer cylinder than by the inner cylinder.

Claim 1
Independent Claim
137 words
A liquid atomizing device comprising a sleeve-shaped body provided with an inner cylinder having a cylindrical inner peripheral surface and an outer cylinder fitted to the front end of the inner cylinder and having a cylindrical inner peripheral surface concentric with said inner peripheral surface of the inner cylinder and a nozzle injecting a liquid against the inner peripheral surface of the inner cylinder, in which said sleeve-shaped body may be secured to a rotational shaft at the rear end thereof concentrically therewith, both of said inner peripheral surfaces of the inner and outer cylinders having a smooth finish thereon and the inner peripheral surface of the outer cylinder having a diameter larger than that of the inner cylinder, and an annular channel opening forward is provided between front ends of the inner and the outer cylinders.
Claim 2
Dependent Claim
