Abstract

A three-way valve comprising a body 2 and a bore 4 having, towards each end, a chamber 6, 10 in communication with supply or exhaust connections 8, 12, in which a spring-loaded two-position hollow spool 20, slidable in the bore, can connect a load connection 34 with the supply or exhaust by opening or blocking one of the chambers in each position of the spool. The spool is moved into its alternative positions by an electromagnet 16. <IMAGE>
