Abstract

Il dispositivo per misurare le quantità di iniezione di pompe di iniezione 11 presenta un elemento 15 attenuatore di iniezione presentante un corpo cavo di intercettazione 27, ad elasticità longitudinale, una molla di pressione 50 ed una strozzatura 48 lato-uscita. L'azione della molla di pressione 50 è contrapposta ad una dilatazione longitudinale del corpo cavo di intercettazione 27. Mediante la cooperazione della strozzatura 48, della molla di pressione 50 ed elemento di intercettazione 27 ad elasticità longitudinale si compensano variazioni della corrente di volume tramite variazioni di lunghezza ad esaurimento a soffietto, cosicché è possibile una corrente di volume uniforme e continua (figura 1).The device for measuring the injection quantities of injection pumps 11 has an injection attenuator element 15 having a longitudinal elasticity interception hollow body 27, a pressure spring 50 and an outlet-side throttle 48. The action of the pressure spring 50 is opposed to a longitudinal expansion of the interception hollow body 27. Through the cooperation of the choke 48, the pressure spring 50 and the interception element 27 with longitudinal elasticity, variations in the volume flow are compensated by variations of bellows exhaustion length, so that a current of uniform and continuous volume is possible (figure 1).
