摘要： In a refrigeration cycle in which the opening of the expansion valve is controlled by the super-heat degree of the refrigerant periodically detected at the outlet of the evaporator, a negative control signal is produced to rapidly change the opening of the expansion valve when the detected super-heat degree has reached zero. As a result, occurrence of the liquid back is prevented.

摘要： An electromagnetic clutch includes a pair of rotatable driving and driven members adapted to be electromagnetically coupled together and uncoupled from each other. At least one of the driving and driven members comprises a pair of concentric annular members both made of magnetizable material and having opposed and radially spaced peripheral surfaces in which annular grooves are formed, respectively. An annular bond member of a non-magnetizable material is swaged into the annular space between the annular magnetizable members and thus into the annular grooves to mechanically connect the magnetizable members as well as to magnetically disconnect them from each other.

摘要： An electromagnetic clutch having an energizing device including a cylindrical yoke assembly composed of a yoke member and a yoke holder, and a winding housed in the yoke assembly. The yoke member has an outer cylindrical wall and an inner cylindrical wall constituting a double wall cylindrical structure, and a doughnut-shaped bottom wall connecting the outer and inner cylindrical walls together. The outer cylindrical wall is tapering in going from the bottom wall toward the upper end, and the inner cylindrical wall has a constant thickness lower portion of a predetermined height contiguous with the bottom wall and a tapering portion contiguous with the constant thickness lower portion and having its thickness successively reduced in going toward the upper end. The inner cylindrical wall has an annular groove formed on its inner circumferential surface in its constant thickness lower portion. When the yoke member and the yoke holder is assembled, the yoke holder is force fitted to the yoke member and a clamping force is exerted on the yoke assembly in such a manner that the latter is plastically deformed to have its material flow into the annular groove of the yoke member to form a joint, whereby the yoke member can be firmly fitted to the yoke holder.

摘要： An electromagnetic clutch comprises a pulley rotatable about a shaft, an armature which is axially movably connected to the shaft and faces a portion of the pulley so as to contact with electromagnetic force thereby coupling the pulley and the shaft, an electromagnet with a winding and a core which has cylindrical face coaxial of the shaft, a part of which core faces to a part of the pulley with small air gap so as to make magnetic circuit, a supporting member which has a cylindrical portion surrounding the shaft with a gap and rotatably supporting the pulley through a bearing, and a flange portion spreading out from the one end of the cylindrical portion. The supporting member is secured to the core of the electromagnet with the flange portion tightly inserted in the cylindrical face of the core, thereby defining an electromagnetic assembly in which a recess for engagement with a machine is formed. The core is precisely press-formed, and the electromagnetic assembly is precisely machined at the outer face of the cylindrical portion of the supporting member and at the recess, on basis of the core. By energizing the winding a magnetic circuit is produced whereby magnetic flux passes through the core, the pulley, and the armature so that the armature is attracted to the pulley to contact therewith.
