Title:
CONTROL VALVE AND MAGNETIC HEAT PUMP DEVICE
Document Type and Number:
Japanese Patent JP2019100430
Kind Code:
A
Abstract:
To provide a control valve for magnetic heat pump device capable of reducing heat loss due to frictional heat.SOLUTION: A control valve 10 is provided in a magnetic heat pump device, and controls inflow and outflow of working fluid with respect to a magnetic material 6, wherein the magnetic heat pump device comprises: a permanent magnet 4 fixed to a rotational shaft 3; and the magnetic material 6 arranged along a circumferential direction on an outer peripheral side of the permanent magnet 4. The control valve comprises: a rotor 11 fixed to the rotational shaft 3; a non-rotary body 12 arranged on an outer peripheral side of the rotor 11; a plurality of spool valves 13 arranged radially so as to make its inner diameter side end surface face an outer peripheral side end surface of the rotor 11 and make its axis face a radial direction of the rotor 11, and regulated so as to be advanceable/retreatable in an axis direction to the non-rotary body 12; and a spring element 14 configured to energize the respective spool valves 13 toward the outer peripheral side end surface. As circumferential profile of the outer peripheral side end surface, the control valve has at least two kinds of profile with a different length of a diameter from a rotation center of the rotor 11.SELECTED DRAWING: Figure 2
