CRUSHABLE BODY FOR POSITION ADJUSTMENT - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240044386 titled 'CRUSHABLE BODY FOR POSITION ADJUSTMENT
Simplified Explanation
The patent application describes a piston assembly that is used to engage two selectively engageable parts. The assembly includes a housing with a piston cylinder, a piston, and an adjuster assembly. The adjuster assembly consists of a piston stroke limiter, which limits the length of the piston's return stroke, and a crushable body that acts between the piston and the piston stroke limiter.
- The piston stroke limiter is designed to restrict the length of the piston's return stroke from an extended position to a retracted position. It includes a spring and a spring guide.
- The crushable body is positioned between the piston and the piston stroke limiter and is capable of reducing in axial length when the extension stroke exceeds the retraction stroke. This ensures that the length of the return stroke is maintained.
- The crushable body is composed of an inner crushable thin-walled tube that surrounds a portion of the piston and an outer crushable thin-walled tube that is mounted around and radially outwards of the inner crushable tube.
Potential applications of this technology:
- Automotive industry: The piston assembly can be used in engines to engage different parts, such as valves or fuel injectors.
- Industrial machinery: The assembly can be applied in various types of machinery that require precise piston movements, such as hydraulic systems or compressors.
Problems solved by this technology:
- Limiting piston stroke: The adjuster assembly with the piston stroke limiter ensures that the piston's return stroke is restricted to a specific length, preventing it from extending too far or retracting too much.
- Maintaining piston length: The crushable body reduces in axial length when the extension stroke exceeds the retraction stroke, allowing the piston to maintain its desired length during the return stroke.
Benefits of this technology:
- Improved precision: The adjuster assembly allows for precise control of the piston's return stroke length, ensuring accurate engagement of the two parts.
- Increased durability: The crushable body acts as a buffer between the piston and the piston stroke limiter, absorbing any excessive forces and protecting the assembly from damage.
- Cost-effective: The use of crushable thin-walled tubes as the crushable body provides a simple and cost-effective solution for maintaining the length of the return stroke.
Original Abstract Submitted
a piston assembly for engaging two selectively engageable parts comprising: a housing defining a piston cylinder; a piston; and an adjuster assembly comprising: a piston stroke limiter configured to limit the length of a return stroke of the piston from an extended stroke position and a retracted stroke position, the piston stroke limiter comprising a spring and a spring guide; and a crushable body, acting between the piston and the piston stroke limiter, the crushable body being arranged to reduce in axial length when a length of an extension stroke exceeds a length of a retraction stroke to maintain the length of the return stroke; wherein the crushable body comprises an inner crushable thin-walled tube surrounding at least a portion of the piston and an outer crushable thin-walled tube mounted around and radially outwards of the inner crushable tube.
