Inside a Refrigeration Thermostat

A refrigeration thermostat is used to maintain the required temperature by automatically controlling the operation of the refrigeration system. It senses the temperature and switches the refrigeration equipment on or off when the set temperature is reached.

Inside the thermostat, the sensing bulb detects temperature changes and transfers the pressure through the capillary tube to the diaphragm. The movement of the diaphragm operates the mechanical linkage and electrical contacts, controlling the compressor circuit according to the temperature setting.

This detailed cutaway shows the adjusting k**b, setting scale, sensing bulb, capillary tube, diaphragm, springs, toggle mechanism, switch contacts, and electrical terminals, giving a clear view of how temperature sensing is converted into automatic electrical control.

Inside a Marine Governor

A detailed 3D cutaway view showing the internal working mechanism of a marine governor. The illustration highlights important components such as flyweights, control spring, spindle, pilot valve, power piston, control sleeve, oil passages, and output mechanism.

The governor plays an important role in maintaining engine speed by sensing speed changes and adjusting the control mechanism accordingly. This visual makes it easier to understand how the mechanical and hydraulic parts work together for stable engine operation.
