Abstract
A multiway valve for controlling a flow of fluid under pressure, includes a valve housing having fluid ports and a plurality of bores in side-by-side parallel disposition substantially at a same level. Each bore is configured for accommodation of a valve spools which are sealed in the bores against the valve housing. The spools have opposite first and second end faces, and include portions of greater diameter and portions of smaller diameter. Acting on the first end face of the spools is an actuation unit for moving the spools in a longitudinal direction to thereby direct a flow of fluid under pressure between the ports, whereas a mechanical coupling mechanism, which is secured to the valve housing, interacts with the second end faces of the spools.
