Title: Spool valve device
Inventor: HIRAKAWA SHIGEKI
IPC: F16K3/24
Filed: 2003-03-14
Abstract: <P>PROBLEM TO BE SOLVED: To provide a spool valve device that is applicable to mass production, and that has less leak.  <P>SOLUTION: This spool valve device 10 comprises a containing member 11, a first diameter part 12, a second diameter part 13, etc. The containing member 11 comprises a first cylinder part 22 and a second cylinder part 23. The first diameter part 12 has a first large diameter land 31, a second large diameter land 32, and a third large diameter land 33. The second diameter part 13 has a middle diameter land 34 and a small diameter land 35. The lands 31, 32, and 33 have equal outer diameter that is larger than outer diameter of the middle diameter land 34. The middle diameter land 34 has larger outer diameter than that of the small diameter land 35. As a spool is parted to the diameter parts 12 and 13, axial length becomes shorter, and bend is less likely to be generated at the time of manufacturing. Yield is thus improved, and the diameter parts 12 and 13 can be efficiently mass-produced. Since the first diameter part 12 has the lands 31, 32, and 33 of similar outer diameter, gap between an outer circumferential surface of the lands 31, 32, and 33 and an inner circumferential wall of the first cylinder part 22 containing the first diameter part can be narrowed. Leak of operating fluid can be very little.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
