1. An apparatus for measuring outside air temperature, comprising:
- a housing provided with input and output openings for feeding a current of outside air through the housing;
a temperature sensor mounted within the housing;
means for moving the ambient air by suction through the housing and across the temperature sensor;
a Venturi nozzle connected to the output opening and provided with a nozzle housing forming an air penetration opening that is connected to the output opening and disposed orthogonally relative to a direction of the Venturi nozzle so as to generate vacuum pressure at the air penetration opening by wind moving through the nozzle housing past the air penetration opening.

Abstract
An apparatus for measuring the temperature of outside air provided with a thermometer mounted in a housing connected to a forced ventilation blower for drawing a current outside air across the thermometer and with a Venturi nozzle having an air penetration opening disposed orthogonally relative to the air current for generating vacuum pressure and prevent reverse flow of air through the housing.

15. An apparatus for measuring outside air temperature, comprising:
-
a housing provided with input and output openings for feeding a current of outside air through the housing; a temperature sensor mounted within the housing; means for moving the ambient air by suction through the housing and across the temperature sensor; a Venturi nozzle connected to the output opening and provided with a housing forming an air penetration opening disposed orthogonally relative to the outside air current in a direction of the Venturi nozzle so as to generate vacuum pressure at the air penetration opening by the outside air current moving through the housing, wherein the Venturi nozzle comprises concentrically aligned, rotationally symmetric upper and lower nozzle components provided with convexly curved semi-surfaces facing and disposed at a predetermined distance from each other so as to determine the suction effect of the Venturi nozzle. - View Dependent Claims (16, 17, 18, 19, 20)
