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 paramagnetic body and is no longer excited by the permanent magnet so as to be displaced by the biasing force of the spring to the second position for flow of the fluid through the fluid passage member.

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 paramagnetic body upon the temperature of the region exceeding the Curie point thereof so as to displace the movable contact to the first position.

A solenoid valve assembly having two bobbins including the solenoids which are co-axially supported by a housing first and second valve bodies slidably supported in each axial bore of the two bobbins and movable independently with respect to energized conditions of the solenoids, an outlet port formed in the housing to receive control pressure from two different pressure sources applied to two inlet ports formed in the housing, a first, second, third and fourth valve core positioned within the housing, a single sleeve of non-magnetic material secured to the valve cores such that the valve cores are positioned within axial bores of the bobbins, passageways for communicating with the outlet and two inlet ports formed in the sleeve and valve cores, the first valve body being of a magnetic material which is axially movable and supported in the sleeve between the first valve core and the second valve core, the second valve body including magnetic material axially movable and supported in the sleeve between the third valve core and the fourth valve core and a member for biasing the valve bodies, respectively, in an axial direction.

Solenoid valve assembly

In an electromagnetically operated valve unit, a stationary core and a spring loaded moving-core are coaxially arranged within an axial bore extending across a lateral plate member of magnetic material, and a U-shaped yoke member of magnetic material has a head portion engaged with the stationary core and a pair of longitudinal arms which are supported by the opposite ends of the lateral plate member and fastened to a bracket. The lateral plate member is formed at its opposite ends with a pair of arms which are engaged with each outer face of the respective arms of the yoke member to uniform a magnetic path of the solenoid coil across the cores, the lateral plate member and the yoke member.
