Claims

[Claims for Utility Model Registration] (1) A female rotor having an outer circumferential portion that is in close contact with the inner circumferential surface of the rotor casing, a depressed portion that is depressed from the outer circumferential portion, and a portion of the female rotor that forms the depressed portion. This is a pump in which a male rotor and a male rotor equipped with blades having blade side surfaces created by the above-mentioned method rotate in opposite directions synchronously in a non-contact state. After the fluid in the pump chamber having the side vane side surface is compressed by the reduction in the volume of the pump chamber, the pump chamber having the leading side vane side of the same vane communicates with the recessed part of the female rotor, and this recess In a pump configured to discharge into a slow discharge path through a recessed portion, a recessed portion into which the blade is fitted from near the point at which communication between the recessed portion into which the blade is fitted and the discharge passage is cut off; The fluid in the depression in which the blade is fitted is discharged into the pump chamber having the side surface of the lagging side of the blade through the gap between the blade and the female rotor until the volume reaches the vicinity of the minimum volume state of the blade. A non-contact pump that features a car designed to (2) A utility model according to claim 1, which is configured so that the blades of the male rotor rotate closely around a fixed circular body having a circular circular portion with which the outer periphery of the female rotor closely contacts. Non-contact pump. (3) Focusing on one blade of the male rotor, reduce the volume of the pump chamber so that the fluid in the pump chamber with the advancing side of the blade passes through the communication path to the depressed part of the female rotor. A non-contact pump according to claim 1 of the utility model registration claim, which allows the flow of water into the non-contact pump.
