HBY combined with rod seals, to absorb impact and surge pressure under heavy load in order to separate high temperature fluids and improve the service life of the seal element.

The main parts of the buffer seal are the static lip, dynamic lip, radial slots, and radial channels. The static lip of the seal is optimized with high flexibility to relieve the interstage pressure. The dynamic lip can minimize the friction and backpressure under high-pressure condition. The radial slots of the buffer seal are designed to reduce the risk of blow-by. The radial channels, a vital element in the whole seal structure, facilitate back-pumping and relieve the pressure.

The main functions of the buffer seal in the hydraulic system include several aspects. First, it buffers the shock pressure or pressure fluctuations produced by the piston rod of the hydraulic cylinder, easing the backpressure. Second, the seal helps cooling down the temperature, prevents the overheat from transmitting to the seal, and reducing heat generated from the piston rod seal during operation. Third, it reduces the friction resistance caused by the piston rod seal in the hydraulic cylinder. In general, the buffer seal provides adequate lubrication to the piston rod seal or other main seals, and it can enhance the gap extrusion resistance. Thereby, it can extend the durability of the seal element.
