Detailed Description

The invention will be further described with reference to the drawings and specific examples.

As shown in fig. 1 to 3: the cylinder body is internally provided with a rotor.

The cylinder body is composed of a cylindrical cylinder sleeve 8 and end covers 9 which are respectively fixed at two ends of the cylinder sleeve and seal the cylinder sleeve. The top of the cylinder sleeve 8 is provided with a window, and a tile-shaped swinging block 3 which can rotate around a hinge shaft (not marked in the figure) is hinged in the window; the intrados 11 of the swinging block is of involute curved surface structure.

The rotor 5 is formed by two wing pipes 5-2 fixed on the rotating shaft. The rotary shaft is composed of a front shaft 5-4 and a rear shaft 5-3 which are respectively supported on an end cover 9 through bearings (not shown in the figure) correspondingly, and a tube shaft 5-1 which is positioned in the cylinder body and has both ends closed by the front shaft 5-4 and the rear shaft 5-3. Two wing pipes 5-2 corresponding to the positions of the swinging blocks 3 are uniformly distributed on the pipe shaft, and an inlet (not shown in the figure) communicated with the two wing pipes 5-2 through the pipe shaft 5-1 is formed in the rear shaft 5-3;

the carrier (not shown) supports a idler gear 14 and a carrier gear 12, and the output gear 4 fixed to the front axle 5-4 is engaged with the idler gear 14 via the carrier gear 12, which is hinged to a link 13 hinged to the swinging block 3 via a link shaft 15.

In order to reduce the pressure loss, sealing ring gaskets 10 are fixed at the ports of the two wing pipes 5-2.

In order to facilitate the pushing of the swinging block 3 to move through the port of the wing tube 5-2 during starting, a starting motor 1 is also fixed on the frame, and a starting gear 2 fixed on the starting motor is meshed with an inertia gear 14.

In order to discharge the leaked fluid in time, a drain pipe 7 is fixed to the bottom of the cylinder.

In order to facilitate cleaning of the cylinder, a drain outlet is arranged at the bottom of the cylinder, and a plug 6 is arranged in the drain outlet.

In the above embodiments, the fluid may be a liquid or a gas.

Working principle:

in use, pressurized fluid is connected to the inlet of the rear axle 5-3 via a conduit; then, the starting gear 2 arranged on the starting motor 1 is utilized to drive the inertial gear 14 to rotate clockwise, and the inertial gear 14 drives the rotor 5 to rotate clockwise through the carrier gear 12 and the output gear 4. When the port of the wing tube 5-2 rotates to the position of the swinging block 3 and contacts with the intrados 11, the pressure fluid pushes the swinging block 3 to swing around the hinge shaft; at the same time, the swinging block 3 drives the inertial gear 14 to rotate clockwise through the connecting rod 13. When the inertia gear 14 reaches a certain rotation speed, the starting gear 2 is separated from the inertia gear 14 by a clutch mechanism (not shown in the figure), and then the inertia gear 14 is driven to rotate by pressure fluid only through a pressure source, and power is output.

It is noted that the intrados 11 is an involute curved surface, and the oscillating block 3 and the rotor 5 are constrained by the cooperation of the output gear 4, the carrier gear 12, the connecting rod 13 and the inertia gear 14 during movement, so that the port of the wing tube 5-2 can always keep contact with the intrados 11 of the oscillating block 3 during the process of pushing the oscillating block 3 to move by pressure fluid, thereby avoiding pressure fluid leakage. When the port of the wing tube 5-2 rotates through the area of the swinging block 3, the port of the wing tube 5-2 contacts with the inner wall of the cylinder sleeve 8, and pressure fluid leakage can be avoided. The invention has the advantages of small fluid pressure loss and high working efficiency.
