ABSTRACT:
A three-way air valve whose housing has connection openings for a compressed air power line, a line running to the load and an air let-off opening, the load opening being joined up with the power opening in one position of the valve and with the air let-off opening in the other position thereof. The housing having the power inlet opening, the load opening and the air let-off opening has an axial hole running through it from end to end for taking up a liner, which may be pushed in from one end of the housing and has airways for the air moving through the valve. Furthermore, the liner has a valve lip. Within the inner hole of the liner, which is open at the end nearest to the valve lip, there is the valve spool which has a valve seat for use with the valve lip. The valve spool is acted upon by the driving rod guided in the housing and by a spring which urges it axially.
