Reservoir with liquid level sensing device

摘要

A reservoir is disclosed which has a tank made of synthetic resin and incorporated a liquid level sensing device whereby the sensing device has a magnetically actuable switch enclosed in a depending hollow tubular portion of the tank and a float having a magnet which is axially slidable on the tubular portion in order to actuate the switch when the magnet and the switch are in proximity with the tank having both upper and lower shells with the upper shell being formed integrally with the hollow tubular portion and one of the shells being formed integrally with a heat shielding skirt portion which surrounds the tubular portion. The heat shielding portion extends into the interior of the lower shell for shielding the tubular portion against the welding heat during the connection of the upper and lower shells.
