Device for use as mechanical load for sports, training equipment has valve(s) in fluid connection with valve body(ies) biased into flow blocking/limiting initial position by spring arrangement, opened by fluid pressure in cylinder chamber

摘要

The device has at least two pistons (7) oppositely movable by a shaft (18) in respective cylinder chambers (5,6) and a fluid connection from each cylinder chamber of a piston to the cylinder chamber of the oppositely moving piston. At least one valve (23,24) is arranged in the fluid connection with at least one valve body that is biased into a flow blocking or limiting initial position by a spring arrangement and opened by a fluid pressure generated in the associated cylinder chamber. There is an arrangement for adjusting the spring force of the spring arrangement.
