Abstract

A valve unit for a dosing device of a fluid has a unit body having a fluid inlet passage, a fluid outlet passage, and, therebetween, an obturator seat housing a ball obturator. An obturator passage is formed in the ball obturator, which is rotatable between an open position, in which the obturator passage fluidically connects the fluid inlet passage to the fluid outlet passage, and a closed position, in which the ball obturator prevents passage of fluid from the fluid inlet passage to the fluid outlet passage. A fluid-tight intake piston, slidingly housed in a piston chamber and integral in rotation with the ball obturator, fluidically communicates with the fluid inlet and outlet passages. Cam means arranged between the unit body and the fluid-tight intake piston cause translation of the fluid-tight intake piston from an advanced position to a retracted position for intaking residual fluid present in the obturator passage.

Abstract

A diagnostic method for solenoid valves includes detecting, at excitation of the solenoid, a variation rate of the supply voltage of the solenoid and comparing it with a predetermined value, generating an error signal if the variation rate is lower than the predetermined value, otherwise, detecting characteristics of the waveform of the solenoid current over a time interval between a moment of excitation of the solenoid and a moment wherein the movable core reaches end-stroke position, comparing the detected characteristics with threshold values, generating an alarm signal if the detected characteristics are lower than the threshold values, otherwise calculating the value of solenoid resistance and comparing it with a minimum resistance value and a maximum resistance value when the solenoid current is in steady state, and generating an alarm signal if the solenoid resistance value is lower than the minimum resistance value or greater than the maximum resistance value.

Abstract

A diagnostic method for solenoid valves comprises the steps of: a) detecting,, at the excitation of the solenoid, the rate of variation over time (dV/dt) of the supply voltage of the solenoid and comparing it with a predetermined value; b) if said variation rate is less than said predetermined value, generating an error signal, otherwise, c) detecting the characteristics of the waveform of the solenoid current over a time interval between the solenoid's moment of excitation and the moment wherein the movable core reaches the end-stroke position; d) comparing the characteristics of the waveform detected with predetermined threshold values; e) if the detected characteristics are less than said predetermined threshold, values, generating an. alarm signal, otherwise f) when the solenoid current is in steady state, calculating the value of solenoid resistance (R) and comparing it with a predetermined minimum resistance value (R0) and with a predetermined maximum resistance value (R1); g) if the value of the solenoid resistance (R) is less than the predetermined minimum resistance value (R0) or greater than the predetermined maximum resistance value (R1), generating an alarm signal.
