Abstract

Pressure regulating valve, which is specially designed for application in the supply circuit to heaters of diesel-type combustión engines, as a means to facilitate the starting of such engines, and being installed between the fuel filter and the heater, essentially it is characterized in that it is constituted from a valve body in one of its end regions has a wide transverse and through hole in which a stem is housed which extends at one of its ends in a threaded section that emerges to the outside and is intended to constitute the means of connection to the corresponding filter, counting such rod with a unidirectional valve that allows the fuel to enter from the filter into the stem itself, leaving it through a calibrated radial hole to access the chamber defined in fig. The through hole in which the said rod is mounted, it being provided that said chamber is munique with a longitudinal passage with which the valvular body is provided, whose passage extends to the opposite end of such valvular body where a counter-pressure tare valve has been provided; with the particularity that said step is in turn communicated with the conduit that is defined in a radial derivation provided between said chamber and the counter-pressure calibrated valve, said radial derivation defining the means of connection to the heater and existing therein.
