Multiway valve for switching a flow of fluid under pressure with parallel disposition of valve bores, and valve assembly kit

A multiway spool valve for controlling a flow of fluid under pressure, comprising:

• a valve housing having fluid ports and a plurality of bores in side-by-side parallel disposition substantially at a same level;
• a plurality of valve spools, each of the spools being disposed in a corresponding one of the bores of the valve housing, whereby the spools and the bores are placed into one-to-one correspondence, wherein each of the spools has opposite first and second end faces, and portions of greater diameter and portions of smaller diameter;
• actuating means acting on the first end face of the spools for moving the spools in a longitudinal direction to thereby direct a flow of fluid under pressure between the ports;
• a mechanical coupling mechanism secured to the valve housing and interacting with the second end faces of the spools for transferring a driving force generated by the actuating means from one spool to another one of the spools;
• and
• sealing means for sealing the spools in the bores against the valve housing.
