Abstract:
The invention discloses a rotation-type flow path switching valve, which includes a driving component and a valve body component connected with a driving shaft. The valve body component includes a valve body, and a spool. The valve body component further includes: a driving disc, and a driven disc which is connected, by means of a first gap linkage mechanism, with the driving disc to transfer an axial movement within a preset swivel stroke of the driving disc. The driving shaft and the spool are connected by means of a second gap linkage mechanism to transfer the axial movement to the spool within a preset swivel stroke of the driving shaft. The valve body component further includes a spring which makes the spool abut against the valve body.
