Beschreibung
Zusammenfassung:	A trochoid oil pump, which enables the endurance to be increased and the reduction of discharge pulsations and noise to be achieved, and in which those results can be realized with a very simple structure. An interdental space (S) constituted by an inner rotor (5) and an outer rotor (6) having trochoid tooth profile or substantially trochoid tooth profile starts a compression stroke in the location of a partition section between an intake port (2) and a discharge portion, and a linking gap (L) is composed by the interdental space and a preceding adjacent interdental space realized in a discharge stroke. The linking gap expands gradually from the start of compression stroke to the discharge stroke.
