ABSTRACT:
A rotary sequence valve comprises a body defining an inlet port and a plurality of outlet ports, a rotary valve member housed within the body and defining a flow passage having an inlet in fluid communication with the inlet port and an outlet sequentially fluid connected to each of the plurality of outlet ports, the defined flow passage outlet being elongate in the direction of movement to maintain a maximum fluid flow connection between the flow passage outlet and an outlet port, the flow passage outlet and outlet ports being configured such that fluid flow from the flow passage outlet to one of the outlet ports ceases before fluid flow from the flow passage outlet to another outlet port commences, and drive means provided for continuously rotating the valve member relative to the body.
