Title:
PRESSURE CONTROL DEVICE AND FUEL FEED DEVICE USING THE SAME
Document Type and Number:
WIPO Patent Application WO/2007/034767
Kind Code:
A1
Abstract:
A pressure control device enabling the easy adjustment of a valve opening pressure
and having a small pressure gradient when a flow is small. A pressure regulator
(10) comprises a ball (31), a seal part (35) closing a flow passage when the ball
(31) abuts thereon, a valve spring (32) abutting on the ball (31) at its one end
and energizing the ball (31) toward the seal part (35), and a retainer (33) allowing
the other end of the valve spring (32) to abut thereon and capable of changing an
energization force by the valve spring (32). The retainer (33) is disposed in
a valve chamber (34) movably along the direction of the flow passage. The energization
force of the valve spring (32) can be properly adjusted by moving the retainer
(33) to change the set height of the valve spring (32). Since a part with spring
property in the device is only the valve spring (32), the valve opening pressure
can be easily adjusted and its dispersion can be suppressed.
