Claims
- 1. A toy of the type including a fluid compressor means in which an improvement comprises:
- said fluid compressor means including a first connecting port serving as a fluid passageway between the exterior of said fluid compressor means and the interior of said fluid compressor means, said fluid compressor means being constructed so as to provide a cycling positive and negative fluid pressure at said port;
- a motor means operatively associated with said fluid compressor means and capable of causing movement of at least a portion of said fluid compressor means, said fluid compressor means providing said cycling positive and negative fluid pressure in response to said movement;
- a flexible fluid line including coupling means located at its respective ends;
- one of said coupling means at one of said ends of said line attaching to said first port so as to connect the interior of said fluid line to said fluid compressor means and provide cycling positive and negative fluid pressure at the other of said ends of said line;
- an output chamber including a second port, said second port serving as a fluid passageway between the exterior of said chamber and the interior of said chamber, the other of said coupling means connecting the other of said ends of said line to said second port and providing cycling positive and negative fluid pressure at said second port in response to said cycling pressure at said first port;
- a piston movably connected to said chamber and means for moving said piston with respect to said chamber in response to fluid pressure within said chamber;
- an implement operatively connected to said piston and movable in response to movement of said piston with respect to said chamber;
- bypass means associated with said chamber and responsive to at least said negative pressure at said second port so as to allow fluid passage through at least a portion of said chamber without movement of said piston with respect to said chamber.
- 2. The toy of claim 1 wherein:
- said piston is located within the interior of said chamber and is capable of reciprocating within said chamber in response to said cycling positive and negative fluid pressure, said implement moving in response to said cycling movement of said piston.
- 3. The toy of claim 2 wherein:
- the outermost periphery of said piston is less than the innermost periphery of said chamber forming a space between the outermost periphery of said piston and the innermost periphery of said chamber;
- said bypass means associated with said chamber comprising said space;
- said chamber including an opening to the ambient environment, said piston interspaced between said second port and said opening;
- said implement being directly connected to said piston whereby if one of said implement or said piston is moved the other is moved and if one of said implement or said piston is restrained from moving the other is restrained from moving such that if said implement is restrained from moving both said positive and said negative pressures at said second port result in fluid passage through said space between said second port and said opening in a direction resulting in equalization of said pressure at said second port compared to fluid pressure in the ambient environment.
- 4. The toy of claim 3 wherein:
- said piston divides said chamber into a portion proximal to said second port and a portion distal to said second port, the volume of said proximal portion increasing and the volume of said distal portion decreasing in response to positive pressure at said second port and the volume of said proximal portion decreasing and the volume at said distal portion increasing in response to negative pressure at said second port, said opening connecting said distal portion to the ambient environment allowing fluid flow between said distal portion and the ambient environment.
- 5. The toy of claim 1 including:
- said means for moving said piston comprising a piston moving means connecting to said chamber, said piston directly associated with said piston moving means, at least a portion of said piston moving means having a hollow interior, said hollow interior connected to said chamber allowing fluid flow between hollow interior and said chamber such that fluid flow into said chamber in response to positive pressure at said second port results in said fluid flow into said hollow interior causing said piston moving means to move said piston in a first direction and fluid flow from said hollow interior back into said chamber causes said piston to move in a second direction.
- 6. The toy of claim 5 wherein:
- said chamber is divided into a first section and a second section, said hollow interior connecting to said second section, said second port connecting to said first section;
- a first valve means located between said first and said second sections and capable of allowing fluid flow from said first section into said second section and inhibiting fluid flow from said second section into said first section;
- a second valve means connecting between said first section and the ambient environment and allowing said fluid flow from said ambient environment into said first section and inhibiting fluid flow from said first section to the ambient environment;
- a third valve means connecting said second section with said ambient environment and allowing fluid flow from said second section to the ambient environment;
- fluid passing from said second port into said first section and through said second valve means into said second section and into said hollow interior in response to positive pressure at said second port, fluid flowing from the ambient environment through said second valve means into said first section in response to negative pressure at said second port, fluid passing from said hollow interior into said second section and through said third valve means to the ambient environment in response to opening of said third valve means, said piston moving in said first direction in response to fluid flow through said first valve means and said piston moving in said second direction in response to fluid flow through said third valve means.
- 7. The toy of claim 6 wherein:
- said piston moving means comprises a flexible hollow and imperforate member, said member connected to said chamber such that a fluid can pass between said chamber and the hollow interior of said member, said member capable of expanding in said first direction in response to fluid flow from said chamber into said member causing said piston to move in said first direction and said member capable of contracting in said second direction in response to fluid flow from said member to said chamber and causing said piston to move in said second direction.
- 8. The toy of claim 7 wherein:
- said member comprises a bellows expandable in said first direction and contractable in said second direction.
- 9. The toy of claim 8 wherein:
- said piston comprises a cylinder having an open end and a hollow interior, said bellows fitting through said open end into said hollow interior.
