摘要： An ultrasonic transducer comprising a first cylindrical member which includes a mechanical vibration amplifying part formed in symmetry around the axis thereof and having a gradually increased cross-sectional area toward a base portion thereof, the base portion having a flat surface perpendicular to the axis thereof, and an annular rigid part formed with the mechanical vibration amplifying part coaxially therewith, the annular rigid part being extended from the outer wall of the base portion axially and radially outwardly to have sufficient rigidity and weight, and the annular rigid part being provided, in the proximity of the outer wall of the base portion, with an annular groove or gap having a predetermined axial depth in order to reduce the diameter of the flat surface. The transducer further comprises a second cylindrical member which includes a backing block of a cylindrical body, a base portion of which is formed with a flange and a flat surface perpendicular to the axis thereof having the larger diameter than that of the flat surface of the first cylindrical member. An ultrasonic transducer portion is interposed between the flat surfaces of the first and second cylindrical members and comprises a pair of piezoelectric elements having flat surfaces perpendicular to the axis of the first and second surfaces, and an electrode plate interposed between the pair of piezoelectric elements. A fastening device pressingly abuts the flat surfaces of the piezoelectric elements against the flat surfaces of first and second cylindrical members and integrally clamps the annular rigid part and the flange of the second cylindrical member to each other in a manner to circumvent said annular groove or gap. The ultrasonic transducer prevents the flexural vibration of the flat surface of the first cylindrical member and prevents cracking of piezoelectric elements to ensure stabilized operations without transitional variations in electric impedance and resonance frequency and to allow continuous vibrating operations in large amplitude over a long period of time.

摘要： An ultrasonic wave fuel injection and supply device includes an ultrasonic wave generating device and a fuel injection nozzle device. The ultrasonic wave generating device in turn includes an ultrasonic transformer, for transforming electrical oscillations into mechanical vibrations, connected to an ultrasonic oscillator, a mechanical vibration amplifier, for amplifying the amplitude of the mechanical vibrations, secured to the ultrasonic transformer, and a vibratory member, having a hollow cylindrically shaped body the peripheral wall of which is secured to the tip of the mechanical vibration amplifier with the axis of the vibratory member being disposed substantially perpendicular to the longitudinal axis of the mechanical vibration amplifier. The vibratory member has its opposite ends open and is disposed within an intake passage of an engine, the same therefore not hindering the flow of fluid through the intake passage. The fuel injection nozzle has its nozzle opening directed toward the peripheral wall of the vibratory member for injecting liquid fuel under pressure onto the peripheral wall. A fuel supply device introduces liquid fuel from a fuel reservoir to the injection nozzle, and a control device controls the amount of fuel being injected through the injection nozzle in response to the running conditions of the internal combustion engine. The ultrasonic wave fuel injection and supply device thus atomizes and scatters the liquid fuel injected onto the peripheral wall of the vibratory member as a result of the ultrasonic vibrations thereof, and the atomized and scattered liquid fuel is supplied to the combustion chamber of an engine, together with air from an air cleaner.
