Abstract: PURPOSE:To make easier the constitution of a small size car heater and make the flame tapered off and stable by making a second combustion cylinder with a smaller or identical diameter compared with a first combustion chamber. CONSTITUTION:A fuel injection value 11 is provided concentrically in a cylindrical whirl chamber 2 formed at the central portion of a whirl wind generating device 1 or a whirler 1, which fuel injection valve atomizes the fuel from the closed end side to the open end side of the whirler, and a cylindrical first combustion cylinder 16 is connected concentrically to the open end of the whirl chamber 2 through a first throttle 15, and the ignition section at the top of an ignition plug 17 is projected at the axial center of the first combustion cylinder 16, and a cylindrical second combustion cylinder 20 is connected concentrically to the outlet of the first combustion cylinder 16 through a second throttle 19. The first combustion cylinder 16 is formed with a diameter larger than that of the whirl chamber 2. The second combustion cylinder 20 has a diameter similar to that of the first combustion cylinder 16. Incidentally no throttle is provided at the outlet of the second combustion cylinder. Since the diameter or the first combustion cylinder 16 is larger than that of the whirl chamber 2, the flame of the mixture gas flows into the first combustion cylinder 16 from the whirl chamber 2 through the first throttle 15 and then suddenly expands to form a stable circulation area for the first combustion cylinder 16, and good flame is secured.

Abstract: PURPOSE:To convey a flagile, small and light solid without damage by putting hair slantingly with the arrangement of the tips in a regular direction and giving up and down vibration. CONSTITUTION:On a base matter 4 consisting of cloth or synthetic fibers, hairs are put slantingly so that the hair tips 3 are arranged in a regular direction of the convey. The base matter 4 is bonded on a slab 5 of metals or the like. A sheet matter 2 is constituted with the hair 3, base matter 4 and slab 5. A vibrator with the use of low frequency oscillator is provided on the sheet matter 2. A pellet 1 is put on the haired surface of the sheet matter 2 to support with the hair tips 3 and the sheet matter is vibrated up and down with the vibrator. The vibration changes to ciliary movement of the hair tips 3 and the pellet 1 proceeds to direction A. The proper vibration condition is set so that the magnitude is the same as or less than the hair length and the frequency is set depending on the convey velocity of the pellet 1. That means the increase of frequency results in the increase in the convey velocity. In this manner, the pellet is conveyed by the ciliary movement of the hair tips 3, and so the damage of pellet 1 in case of crashing of each other pellets is prevented because of week shock.
