Abstract

PURPOSE: To reduce magnetic loss of an electromagnet by freeing from a clearance made between a core and a hole formed by a wound frame of a vacuum adiabatic shell and prevent heat from entry into a valve case by fixing the core onto the valve case by use of an adiabatic rod with low heat conduction.
CONSTITUTION: A staged cylindrical valve 1 constituted of a cylinder 2, valve element 3, contricted part 4, and rubbing part 5 is fit in a valve case 22. A valve seat 15 is located between holes 23, 24 of the valve case 21, on or off which the valve element 3 reciprocates. The valve case 21 is constantly applied with an effort of a flexible member 19 in the direction of an arrow. A flange 22 of the valve case 21 is connected to a magnetic core 27 by an adiabatic rod 26 low in heat conductivity. The core 27 with a membrane of Teflon on it is inserted rubbing in a hole 32 of a wound frame 35 of the vacuum adiabatic cylinder 31, One end of the adiabatic holder 42 is connected with an end 38 of the wound frame 35 and the other end is firmly on a ring 47 fixed on a flange 17 of a pipe 18.
