Claims

[Scope of utility model registration request]

A stator comprising a plurality of arcuate teeth formed at equal intervals in the circumferential direction, a rotor consisting of a trochoidal tooth profile that rotates within the stator while meshing with the arcuate teeth, and a rotor that holds the stator from both sides. ,
a pair of plates having a required clearance between them and the rotor; a drive shaft connected to a hole formed in the axial center of the rotor; and a drive shaft that is attached to the rotor to prevent the drive shaft from slipping out. In the trochoid type hydraulic device, which includes a spacer and sucks and discharges pressure oil by volume variation accompanying rotation of the rotor in a space defined by the arcuate teeth of the stator and the tooth profile of the rotor. By forming a recess with a larger diameter than the hole around the hole in the axis of the end face of the rotor, and fitting the spacer with a sealing mechanism in the recess,
A recess that maintains liquid tightness between the high pressure side and the low pressure side, forms a communication hole in the spacer that communicates the high pressure side and the low pressure side, and opens the communication hole to the high pressure side in the plate that contacts the spacer. A trochoid type hydraulic device characterized by forming a section.
