  • Temperature sensing valve
    Patent number: 4407448
    Abstract: A temperature sensing valve includes a casing having an internal fluid passage member formed therein, a permanent magnet mounted in the casing, a valve body which includes a magnetically soft, amorphous metal member supported in a thermally sensitive region of the casing for movement between a first and second position and being magnetically coupled to the permanent magnet so that flow through the fluid passage member can be interrupted in response to magnetic excitement by the permanent magnet of the valve body, and a spring for urging the valve body in a first direction to permit fluid flow through the fluid passage member wherein when the temperature of the second thermally sensitive region is below the Curie point of the second valve body, the valve body is excited by the permanent magnet to maintain the fluid passage member closed against the biasing force of the spring whereas when the temperature of the thermally sensitive region reaches the Curie point of the valve body, the valve body constitutes a p

  • Temperature switch having a magnetically soft amorphous metal member
    Patent number: 4383231
    Abstract: A temperature switch includes a housing, a fixed contact positioned in the housing, a movable contact member mounted in the housing carrying a movable contact and urged to first and second positions where the movable contact is in abutment with or displacement from the fixed contact, respectively, a permanent magnet mounted in the housing, a thermally sensitive member mounted in the housing so as to be exposed to a region the temperature of which is to be determined wherein the thermally sensitive member includes a magnetically soft, amorphous metal member and is magnetically coupled to the permanent magnet, and an operating member which includes magnetic material wherein a first end thereof engages the movable contact member and a second end thereof opposite the first end is attracted to the thermally sensitive member against the resilience of the movable contact member, thereby causing displacement of the movable contact to the second position and wherein the thermally sensitive member includes a paramagnet
