WAX-PELLET THERMOSTAT A wax-pellet thermostat has a valve seat, a piston secured to the valve, a guide member slidably mounted on the piston, a valve secured to the guide member, a diaphragm secured to the guide member, and a wax provided in the cylinder. A gap is provided in the guide member around the piston so as to accumulate coolant entered along the piston. The gap is provided to discharge the coolant from the guide member when the wax expands to cause a part of the diaphragm to enter into the gap. |
