Document Type and Number:
Japanese Patent JP2020012414
Kind Code:
A
Abstract:
To provide a hydraulic motor installed in a backwash type filtering device which realizes energy saving that suppresses fuel consumption without increasing the number of components.SOLUTION: The present invention relates to a hydraulic motor 100 for a backwash type filtering device W comprising: a housing 110; a rotor 130 accommodated in the housing 110; and a rod-like second rotation part 140. An inner peripheral side face of the housing 100 is formed in a trochoid curve shape and an inflow pipe 50 for making a fluid flow in and an outflow pipe 60 for making the fluid flow out are connected to the housing 110. The second rotation part 140 is connected to a first rotation part 8 which rotates a backwash arm 20, and rotates the first rotation part 8 with its own rotation. An outer peripheral side face of the rotor 130 is formed in an inner envelope shape corresponding to the trochoid curve shape, a center hole 132 is provided in its central part, and an inner peripheral side face of the center hole 132 is inscribed to the second rotation part 140.SELECTED DRAWING: Figure 2
