摘要： A fuel injecting device and method of controlling the fuel injection device. The fuel injection device includes a cylindrical body, a needle whose end includes with a head forming a valve on a seat supported by the end of the cylindrical body, an actuator made of an electroactive material, including a rod and that displaces the head such that the valve is opened, and a prestressing device holding the needle and a counterweight such that they are pressed against the rod opposite end. The needle extends coaxially to the cylindrical body in a form of a rigid bar and axially resonates when exposed to axial pulses at a determined excitation frequency by the actuator.

摘要： A fluid injection device including a protruding needle. One end of the needle forms a valve and can be moved between a closed position, in which the valve seals the fluid-release opening, and an open position, in which the valve is positioned at a controlled distance from the opening. Movement of the valve between the closed position and the open position is produced by the controlled intrinsic extension of the protruding needle.

摘要： The invention relates to an injector including a needle mounted in a nozzle and having an end defining a valve, the needle being connected at the other end to an actuator including first, second and third portions, the first and third portions being provided on either side of the second portion, the three portions being tightened together in order to form a block having two axially opposite limits, the first portion being connected with the needle at one of said limits, and an excitation means for vibrating the second portion according to setpoint period τ. According to the invention, the length between the two limits of the block is such that the propagation time T of the acoustic waves generated by the vibrations of the second portion of the actuator and running along that length meets the equation: T=n*[τ/2], where n is an integer positive multiplication coefficient different from zero.

摘要： An injection device for injecting pressurized fluid includes a housing, an actuator, and an energizing unit. The housing includes at least one axial cavity filled with pressurized fluid. The actuator includes a stack with a first transverse face extended axially by a penetrating member and a second transverse face axially opposite the first. The stack includes at least one electroactive part including an electroactive material. The member includes a piston engaged in the cavity and forming a fluidic connection between the actuator and the housing. The energizing unit sets the electroactive part of the actuator in vibration with a set period τ. The penetrating member includes an axial length such that the propagation time T of the acoustic waves produced by the vibrations of the electroactive part of the actuator and traveling along this length satisfies the following equation: T=[2n+1]*[τ/4], where n is a positive integer coefficient.
