Abstract

The auxiliary hydraulic drive for the slide of a fluid catalytic cracking (FCC) slide valve comprises a push rod (3) which can be connected to the slide by a clamp (31) operated by a spring-loaded clamping piston (32). This is operated by fluid passing through a bore (60) in the main piston (20) with a branch (61) into the chamber (62) containing it.
