PUMP ACTUATOR WITH IMPROVED FATIGUE LIFE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18747235 titled 'PUMP ACTUATOR WITH IMPROVED FATIGUE LIFE
The patent application describes a pump actuator designed to improve fatigue life through various features.
- The pump actuator body has a pad with a concave surface feature on the plunger facing side.
- The opposite roller facing surface of the pad is treated with shot peening for enhanced durability.
- The plunger facing surface is recessed and offset from the radial end, providing structural strength.
- A cylindrical wall is defined between the radial end and the plunger facing surface for added support.
- These features work together to improve the pump actuator body's fatigue life without adding mass.
Potential Applications: - This technology can be used in various types of pumps where durability and longevity are crucial. - It can also be applied in hydraulic systems, automotive engines, and industrial machinery.
Problems Solved: - Increases the fatigue life of pump actuators. - Enhances the durability of components in high-stress environments. - Improves the overall performance and reliability of pump systems.
Benefits: - Extended lifespan of pump actuators. - Reduced maintenance and replacement costs. - Enhanced efficiency and performance of pump systems.
Commercial Applications: - Pump manufacturing companies can integrate this technology into their products to offer more reliable and durable pumps to customers. - Industries relying on pumps for their operations can benefit from increased uptime and reduced maintenance costs.
Questions about the Technology: 1. How does the concave surface feature on the pad contribute to the pump actuator's performance? 2. What are the specific advantages of using shot peening on the roller facing surface of the pad?
Frequently Updated Research: - Stay updated on the latest advancements in pump actuator technology to ensure optimal performance and reliability in various applications.
Original Abstract Submitted
A pump actuator for use between a cam and a pump comprises a pump actuator body having a pad defined between a plunger facing surface and an opposite roller facing surface, where the plunger facing surface is recessed into the pump actuator body and offset from a radial end. The pump actuator body further comprises a cylindrical wall defined between the radial end and the plunger facing surface. A concave surface feature is formed on the pad on its plunger facing surface. The opposite roller facing surface of the pad is provided with a surface enhancing treatment comprising shot peening. These features, separately or in combination, provide mass-neutral improvements of the pump actuator body's fatigue life.
