ABSTRACT:
A liquid level control apparatus which detects a liquid level in a tank employed, for example, in ice making equipment, to thereby trigger a control operation. The level control apparatus comprises a tank containing a body of liquid, a float movable in response to the vertical movement of the surface of liquid within the tank, a hollow case having a closed top and an open bottom, and a guide member disposed within the case for guiding the vertical movement of the float. The hollow case is arranged so that the open bottom thereof is closed by the rising liquid to thereby from a hermetically closed chamber within the case. An upstanding tubular member extends into the hollow case such that the lower end of the tube defines a level of liquid at which the hermetically closed chamber is formed. The chamber thus formed is effective for preventing the guide member from being immersed in the liquid to assure smooth movement of the float.
