| 摘要 | A rotary engine is provided with a device for cushioning the blows of a radially movable chamber partition against the rotor of the engine. The device includes a piston that enters a fluid filled compartment as the partition moves radially inwardly, the compartment having a restricted exit for the fluid. | ||||||
| 权利要求 | 1. In a rotary engine having a rotor with a piston projection in an annular chamber, the piston projection being arranged to sweep around the annular chamber as the rotor rotates, a chamber partition that can ride over said projection, and a spring urging the partition towards the rotor, a cushioning device comprising a piston movable with the partition, a fluid filled compartment which the piston enters as the partition closely approaches the rotor, an outlet through which the piston can force the fluid from the compartment, and a fluid reservoir beyond the outlet and from which fluid can flow back into the compartment when the partition and piston are forced by said projection away from the rotor. 2. The rotary engine as claimed in claim 1 wherein the piston comprises a lip on the partition radially outward from the annular chamber. 3. The rotary engine as claimed in claim 1 wherein the fluid reservoir is located radially outward from the annular chamber, the partition as it rides over said projection reciprocates in the fluid reservoir, the compartment being within the reservoir and the reservoir being filled with fluid to a level so that the compartment is immersed in the fluid. 4. The rotary engine as claimed in claim 1 wherein the outlet through which the piston can force the fluid from the compartment is located in a wall of the compartment. 5. The rotary engine as claimed in claim 4 wherein a screw is mounted to close the outlet partially and adjustably. |
