The utility model relates to a temperature regulating cam for a pressure type temperature controller, in particular to a high-pressure four-area temperature regulating cam for the pressure type temperature controller. As is shown in the picture 3, the peripheral edge of the temperature regulating cam is composed of six segments of curves which are mutually connected, and the radiuses of the six segments of curves are gradually increased in the anti-clockwise direction. The four segments of curves with the largest arc lengths in the curves form four different temperature areas which have the quick-freezing function, the freezing function, the freshness keeping function and the refrigerating function respectively. An arc protrusion is arranged between the first segment of curve and the second segment of curve and an arc protrusion is arranged between the second segment of curve and the third segment of curve, wherein the two arc protrusions serve as temperature area transformation points. The high-precision fou
