Abstract

Abstract @ An ultrasonic fuel injection nozzle (1) for e.g. an internal combustion engine comprises an ultrasonic vibration generating means (100) and a vibrating element (14) connected to aid vibration generating means (100) so as to be vibrated thereby, said vibrating element being formed at its forward end with a concentrically stepped portion (32) to which liquid fuel is delivered to be atomized at the edges of the steps. Liquid marerial atomized in similar fashion is used for spray drying, humidifying and so on.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 53 words
Ultrasonic vibration method of atomizing a liquid material by vibrating a vibrating element (14) by means of ultrasonic vibration generating means (100), characterized by forming an edged portion (32) at the forward end of said vibrating element, and delivering a liquid material to and along said edged portion to atomize the liquid material.
Claim 2
Dependent Claim 53 words
Ultrasonic vibration method of atomizing a liquid material by vibrating a vibrating element (14) by means of ultrasonic vibration generating means (100), characterized by forming an edged portion (32) at the forward end of said vibrating element, and delivering a liquid material to and along said edged portion to atomize the liquid material.
Claim 3
Dependent Claim 34 words
A method according to claim 1, wherein said vibrating element is continuously vibrated, and the delivery of the liquid material to the edged portion of the vibrating element is either intermittently or continuously effected.
Claim 4
Dependent Claim 44 words
A method according to claim 1 or 2, wherein said liquid material is liquid fuel for use in an internal combustion engine such as a diesel engine, gasoline engine or the like, or an external combustion engine such as a burner or the like.
Claim 5
Dependent Claim 23 words
A method according to claim 1 or 2, wherein said liquid material is a suspension from which powdered medicine is to be produced.
Claim 6
Independent Claim 16 words
A method according to any preceding claim, wherein said.edged portion (32) is of a stepped configuration.
Claim 7
Dependent Claim 115 words
An ultrasonic injection nozzle comprising an ultrasonic vibration generating means (100), an elongated vibrating element (14) connected at one end to said ultrasonic vibration generating means and having an edged portion (32) at the other end, a needle valve (34) slidably mounted on said vibrating element adjacent said other end having said edged portion (32), a needle valve holder (50) adapted to hold said needle valve for slidable movement and cooperating with the needle valve to define a supply passage (62) for liquid material at the edged portion (32) of the vibrating element (14), and spring means (80) normally urging said needle valve toward said holder (50) to close said liquid material supply passage (62).
Claim 8
Dependent Claim 115 words
An ultrasonic injection nozzle comprising an ultrasonic vibration generating means (100), an elongated vibrating element (14) connected at one end to said ultrasonic vibration generating means and having an edged portion (32) at the other end, a needle valve (34) slidably mounted on said vibrating element adjacent said other end having said edged portion (32), a needle valve holder (50) adapted to hold said needle valve for slidable movement and cooperating with the needle valve to define a supply passage (62) for liquid material at the edged portion (32) of the vibrating element (14), and spring means (80) normally urging said needle valve toward said holder (50) to close said liquid material supply passage (62).
Claim 9
Dependent Claim 17 words
An injection nozzle according to claim 6, wherein said edged portion (32) is of a stepped configuration.
Claim 10
Dependent Claim 47 words
A vibrating element for use in an ultrasonic injection nozzle as claimed in claim 6 or 7, said element being formed around its outer periphery with a multi-stepped, edged portion (32) having at least two steps, said edged portion being adapted to be supplied with a liquid.
Claim 11
Dependent Claim 18 words
A vibrating element according to claim 8, wherein said multi-stepped, edged portion (32) has a progressively decreasing diameter.
