Detailed Description

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

As shown in fig. 1 to 3: the cylinder body is 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 inner arc surface 11 of the swinging block is of an involute curved surface structure.

The rotor 5 is composed of two wing tubes 5-2 fixed on the rotating shaft. The rotating shaft is composed of a front shaft 5-4 and a rear shaft 5-3 which are correspondingly supported on an end cover 9 through bearings (not shown), and a pipe shaft 5-1 which is positioned in the cylinder body and is sealed at two ends by the front shaft 5-4 and the rear shaft 5-3. Two wing pipes 5-2 corresponding to the position of the swing block 3 are uniformly distributed on the pipe shaft, and an inlet (not marked 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;

an inertia gear 14 and a carrier gear 12 are supported on the frame (not shown), and the output gear 4 fixed to the front shaft 5-4 is engaged with the inertia gear 14 through the carrier gear 12, and the inertia gear is hinged to a link 13 hinged to the swing block 3 through a link shaft 15.

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

In order to facilitate the swinging block 3 to be pushed to move through the port of the wing pipe 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 the cleaning of the cylinder body, a drain outlet is arranged at the bottom of the cylinder body, and a plug 6 is arranged in the drain outlet.

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

The working principle is as follows:

when in use, pressure fluid is connected with the inlet of the rear shaft 5-3 through a pipeline; then, the starting gear 2 arranged on the starting motor 1 is used for driving the inertia gear 14 to rotate clockwise, and the inertia 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 pipe 5-2 rotates to the position of the swinging block 3 and is contacted with the intrados 11, the pressure fluid pushes the swinging block 3 to swing around the hinge shaft; at the same time, the swing block 3 drives the inertia 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 disengaged from the inertia gear 14 through a clutch mechanism (not shown), and then the inertia gear 14 is driven to rotate by pressure fluid only through the pressure source, and power is output.

It is worth noting that the inner arc surface 11 is an involute curved surface, and the swinging block 3 and the rotor 5 are cooperatively constrained by the output gear 4, the carrier gear 12, the connecting rod 13 and the inertia gear 14 in the process of moving, so that the port of the wing pipe 5-2 can always keep contact with the inner arc surface 11 of the swinging block 3 in the process of pushing the swinging block 3 to move by pressure fluid, thereby avoiding the leakage of the pressure fluid. When the port of the wing pipe 5-2 rotates past the region of the oscillating block 3, the port of the wing pipe 5-2 comes into contact with the inner wall of the cylinder liner 8, and leakage of the pressure fluid can be avoided as well. It is thus clear that the utility model discloses fluid pressure loss is little, and the acting is efficient.
