Abstract
A toy is constructed utilizing an air compressor to supply cycling positive and negative fluid pressure to an output cylinder. A piston is associated with the output cylinder and moves with respect to the output cylinder in response to cycling fluid pressure supplied to the output cylinder. Movement of the piston in turn moves an implement operatively connected to it. With respect to at least negative pressure, the piston or a valve element connected therewith is constructed so as to permit air to move through the cylinder without movement of the piston in the event that the implement is, for any reason, reasonably restrained against movement. The movement of the fluid through the cylinder without concurrent piston movement avoids possible damage to whatever is restraining the implement against movement and additionally avoids possible damage to the toy.
