Progressive hydraulic cushions are devices used in various applications, such as automobiles and industrial machinery, to absorb shock and reduce vibrations. They work by using a fluid-filled chamber that compresses under pressure, providing a gradual resistance to sudden impacts. This design helps to protect components and improve overall performance. These cushions are particularly effective because they offer varying levels of resistance depending on the force applied. As the impact increases, the hydraulic fluid is forced through smaller openings, creating more resistance. This progressive action helps to minimize damage and enhance comfort during operation, making them valuable in many engineering fields.
