Latest Patents

Fujikawa's latest patents include a buffered valve and a breaker valve. The buffered valve features a longitudinal passage leading to a valve chamber, which is divided by a spacer into front and rear chambers. A normally closed main valve member in the front chamber blocks the longitudinal passage, while a sub-valve in the rear chamber is biased toward the port in the spacer by a coil spring. This design allows for a buffered valve action during both opening and closing phases. The breaker valve, on the other hand, includes a main fluid passageway and an auxiliary passageway that intersects it. A spool is slidably mounted in the auxiliary passageway, and upon an emergency, the spool can shut off the main passageway while generating an alarm.
