Integration of a thermostat in the recycling system of the vehicular exhaust gas recirculation (EGR) system
First Claim
1. A thermostat assembly for integration in an exhaust gas recirculating system of a vehicle comprising:
- a casing having a coolant inlet nozzle and a coolant output channel, and having a multifaceted body having a tabular portion which defines a thermostatic valve housing, a nozzle for fixing a closing/sealing terminal having a central projection containing a centered blind hole, the tubular portion providing access to a chamber having a ring wall forming the coolant inlet nozzle and supporting a shaped flange having holes for receiving screws therein, a smaller diameter by-pass passage located at a bottom of the chamber and aligned with a central axis of the tubular portion for linking the chamber to a connection duct for providing access to the coolant output channel projected along a tubular projection, a cylinder shaped central projection located at a bottom of the smaller diameter bypass passage having a tip having a blind hole.

Abstract
The invention relates to the control of the temperature of recirculated exhaust gas and oil, by means of the placement of a thermostat between an oil/water heat exchanger and a water/exhaust gas exchanger. The thermostat comprises a multifaceted casing (1), in which there is a tubular portion (2) having access to a chamber (7); and, at the bottom of the chamber (7), there is a smaller diameter by-pass passage (11), through which the chamber is linked to a connection duct (12) having access to the output channel (13) that is projected along the tubular projection (14), wherein the thermostatic valve is integrated to the casing (1) by being placed inside the chamber (7), along the tubular portion (2).
