Abstract

PURPOSE:To provide rotary motion in any place in such a case that a large engine cannot be used in a narrow place. CONSTITUTION:A rotor 2, provided with two driving nipples 6 partially different in thickness, is fitted to the inside of an outer cylinder 1 through a shaft 3. The rotor 2 is rotated clockwise with the driving nipples 6 as the feed oil ports, and the pressure, supplied to the rotor 2, of an inner pressure chamber 4 is set to be externally higher than driving pre-load.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power engine that uses hydraulic pressure to drive and rotate a rotor.

0002

2. Description of the Related Art There are presses, trucks, and cranes that linearly utilize large hydraulic output, but they are not currently used as engines that rotate by converting linear motion into circular motion.

0003

[Problems to be Solved by the Invention] Therefore, when it is impossible to use a large engine in a narrow space, it is believed that the present invention will make it possible to provide rotational motion in any space.

0004

[Means for Solving the Problems] From the above viewpoint, the present invention makes it possible to apply rotational motion to any location as required, and this will be explained based on the drawings (
1) The outer cylinder has an inlet and an outlet for oil from a hydraulic pump (not shown), and two nipples (6) and (6'). Rotor (
2) (2) (2) The inner cylinder (10) is fixed to the shaft (3) and provided to rotate inside (1). Additionally, lids (9) (9) will be attached to the front and rear of this engine, respectively.

[0005]

[Operation] The present invention is configured as described above, and if hydraulic pressure from the high pressure pump is sent to the nipple (6), the drive pressurized chamber (
7) High pressure is generated on the primary side to rotate the rotor (2) to the secondary side.If the rotor (2) is sent from (6'), it will rotate in the opposite direction. The outer cylinder (1) and the inner cylinder (10) are in contact with each other at an angle of about 30 degrees from the center, and by inserting a leak-proof plate in this interval to prevent oil pressure leakage, it is possible to easily close the drive pressurized chamber. (7) The pressure on the primary side can be increased.

[0006]

As described above, the drive engine can be used in a wide range of applications, including use of ultra-high pressure, use as a high-speed rotating machine, underwater work, and continuous operation of rotation and stop.
