Claims

[Scope of utility model registration request]

In a pump comprising a pair of gear rotors rotatably engaged with each other through shafts in a pump housing having an inlet and a discharge port, which of the two side surfaces in the clearance formed between the opposing side surfaces of the gear rotor and the housing side surface A plurality of concentric annular or radial spiral grooves are recessed in the housing, and a liquid reservoir for discharging the intruded resin is formed on the side surface of the housing surrounding the outer periphery of the rotor shaft, and a liquid reservoir is formed in the housing bearing hole or on the rotor shaft circumferential surface following the liquid reservoir. A resin pressure pump characterized by having a forced relief groove.
