Abstract
PURPOSE: To decrease noises and prevent the seizure during the shut-off operation, by enclosing rotary rubber vanes with a first and a second casings.
CONSTITUTION: Liquid discharged by the revolution of the rubber vanes 13 is temporarily reserved in a discharge chamber 17 defined by the first casing 10 and the scond casing 17 and is then discharged from a discharge port 18. Because the first casing 16 and is then discharged from a discharge port 18. Because the first casing 10 containing the rubber vanes 13 is surrounded by the discharge chamber 17 containing the liquid, the liquid serves as a silencer to greatly decrease the noise due to the rubber vanes 13 and moreover suppresses the heating due to the friction between the rubber vanes and the first casing. Since the quantity of the liquid in the discharge chamber 17 is much higher than that in a pump chamber 21, the quantity of retained water is large. Therefore, the rise in the liquid temperature during the shut-off operation is delayed and the seisure is prevented.
