Document Type and Number:
WIPO Patent Application WO/2014/021361
Kind Code:
A1
Abstract:
[Problem] To provide an electromagnetic valve system whereby, while ensuring safety when a power supply is interrupted, it is possible to reduce power consumption. [Solution] Provided is an electromagnetic valve system (10) for carrying out a compressed air supply to and evacuation from a plurality of air chambers (3) of massage instruments (2) of an air-type massage device (1), comprising: a plurality of first electromagnetic valves (30) which are connected to each air chamber (3) via supply tubes (60); a second electromagnetic valve (40) further comprising a first aperture (47-1) which communicates with external air; and a plurality of first check valves (51) which are disposed within a header (20) in an intermediate location between the second electromagnetic valve (40) and each air chamber (3) with a connection tube (62) therebetween, and allow air to pass from the air chambers (3) toward the second electromagnetic valve (40) only when air pressure on the second electromagnetic valve (40) side is lower than air pressure on the air chamber (3) side. The first electromagnetic valve (30) is a memory-type electromagnetic valve which preserves either a first or second state which is in effect even if a supplied voltage is less than or equal to a given value. The second electromagnetic valve (40) is an auto-disengage type electromagnetic valve which switches to the second state when the supplied voltage is less than or equal to the given value.
