Rotary disk valve for controlling cooling circuit in vehicle, has housing including two coaxially arranged rotary disks rotatable respectively about predetermined angular range, so as to block or release fluid ports

摘要

The valve (10) has a housing (12) including multiple fluid ports (16) and two coaxially arranged rotary disks (20, 28) rotatable by a common drive i.e. electromotor (32). The rotary disks are rotatable respectively about a predetermined angular range, so as to block or release the fluid ports, where the rotary disks are rotated relative to each other over a part of the angular range. The rotary disks are coupled with each other in a rotational direction via a spring (34), where the rotating movement of the rotary disks is limited by a stop (26).
