Abstract (en)
[origin: WO2010031936A1] The invention relates to an injector (7) having an injection axis (AB) and comprising: a housing (2) including an axial cavity (20); an actuator (3) including an electrically active portion (30) and having a first front surface (31) extending in the form of a penetrating member (33), and a second front surface (32) opposite the first one (31), the actuator (3) being mounted in the housing (2) and the member (33) including a piston (330) inserted into said cavity (20) and defining a fluidic link between the actuator (3) and the housing (2); an excitation means for vibrating the electrically active portion (30) of the actuator (3) at a setpoint period t. According to the invention, the penetrating member (33) has a length (L) such that the propagation time (T) of the acoustic waves running therethrough corresponds to the equation: T = [2n+1]*[t/4], where n is a positive-integer multiplier coefficient.
