There is provided a spool valve assembly with a housing defining ports, one of the ports being a fluid inlet port. The spool valve assembly has a trigger member having a channel and being selectively longitudinally slidable relative to the housing between a first position and a second position. Two spools receive the trigger member, the spools each being slidable relative to the trigger member and relative to the housing, from a first position to a second position. The spool valve assembly is configured such that, upon supply of a fluid to the inlet port: the spools are urged to their first positions when the trigger member is in its first position, to permit fluid communication between the inlet port and a region between a trigger end of the housing and the spools, and the spools are urged to their second positions when the trigger member is in its second position, to permit fluid communication between the inlet and a cylinder port. |
