ABSTRACT:
An aspirator for a pneumatic thermostat including a slit restriction which provides a relatively thin and wide jet of air. The large surface area of the flat jet entrains a substantial volume of ambient air and results in a large ambient air flow past the thermostat. The slit restriction is formed either of a shallow channel in a portion of the aspirator housing or of a cutaway portion in a relatively thin sheet of material interposed between two housing halves of the aspirator.
