A multi-port rotary disc valve adapted to allow fluid flow from at least one fluid source to a plurality of destinations, comprises a stator with fluid flow ports including a plurality of individual ports and at least one common port. Each of the individual ports is adapted for fluid communication with at least one of the destinations, and the one common port is adapted for fluid communication with the source. The individual ports are arranged in spaced apart relationship within an individual ports' stator sector having a stator sector angular length. The valve further comprises a rotor having at least a first, a second and a third rotor sector with channels arranged therein, being opened to the atmosphere or adapted to connect the fluid flow ports of the stator between them in a plurality of predetermined combinations. The first, second and third rotor sectors have a first, second and third rotor sector angular length, respectively, wherein the first and the second rotor sectors are spaced from each other and their angular length is at least equal to said stator sector angular length. The third rotor sector is located at least partially between the first and second rotor sectors.

Rotary disc valve

A multi-port rotary disc valve comprising a stator with a plurality of fluid flow ports and a rotary distributor with a plurality of channels arranged in a channel pattern. The channels are adapted to connect the ports between them and/or to the environment in a plurality of predetermined combinations, each combination being associated with an angular position of the rotary distributor with respect to the stator. The succession of combinations performed during a full or partial unidirectional turn of the rotary distributor consitute a predetermined sequence. The rotary distributor comprises a rotor and a mask mounted movably thereon, the rotor and the mask accommodating the plurality of channels. The mask is adapted to change the channel pattern by changing its position with respect to the rotor, thereby enabling the rotary disc valve to perform different predetermined sequences corresponding to different positions of the mask.
