Abstract
A bypass valve with selective characteristics for controlled and adjustable dashpots. It has pressure-activated check valves that are reversed by means of a slide that can assume two positions and is activated by an electromagnet. Springs can be designed to dictate the characteristic of the dashpot independent of the type of piston employed.
