Abstract

Ein Kühlkreislauf für einen Kraftfahrzeugantrieb, bei dem der Motor (1) mit mindestens einem Radiator (6) über eine Zufuhr- und eine Abfuhrleitung (3, 8) verbunden ist, weist einen Thermostat (4), ein Bypass-Ventil (5) und eine Umwälzpumpe (2) auf. Das Bypass-Ventil (4) ist direkt in den Thermostat (5) integriert und in Form von Öffnungen ausgebildet, die in dem Arbeitselement des Thermostats (4) vorgesehen sind, welches in Abhängigkeit von der Kühlmitteltemperatur den Thermostat (4) öffnet oder schließt.

A cooling circuit for a motor vehicle drive, in which the motor (1) is connected to at least one radiator (6) via a supply and a discharge line (3, 8), has a thermostat (4), a bypass valve (5) and a circulation pump (2). The bypass valve (4) is integrated directly into the thermostat (5) and is designed in the form of openings which are provided in the working element of the thermostat (4) which opens or closes the thermostat (4) depending on the coolant temperature.
