Title: Pilot type pressure reducing valve
Inventor: WATANABE KENICHI
IPC: G05D16/16
Filed: 1990-03-15
Abstract: PURPOSE:To prevent the occurrence of a chattering phenomenon by providing a path to supply a primary fluid to the upper part of only a 1st piston out of plural ones in an open state of a pilot valve and also providing a pore to secure linkage between the upper space of the 1st piston and that of another piston. CONSTITUTION:A primary fluid is supplied into a piston chamber 26a of a 1st piston 26 via a pilot valve 42. Thus the fluid flows partly into a piston chamber 28a of a 2nd piston 28 through a pore 29. However the flow rate of supplied fluid is small since the opening amount of the valve 42 is small as long as the reducing pressure ratio is large with a small flow rate. At the same time, the amount of fluid flowing out through the pore 29 is also small. Thus the fluid flows out mistakenly through an orifice 28c of the piston 28. As a result, the driving force enough to open a 2nd main valve 22 is not produced by the piston 28. Therefore the valve 22 is kept closed. Then the valve 42 is never closed suddenly and therefore a chattering phenomenon is prevented.

IPC: G06F1/02
Filed: 1991-03-29
Abstract: PURPOSE:To reduce the cost and to reduce other limitations for an arc tangent data generating circuit by maintaining a high processing speed and at the same time reducing the capacity of a look-up table. CONSTITUTION:A method which generates the tan<-1> data with an approximate operation using the linear interpolation is applied. A look-up table 3 does not store the tan<-1> date (value of Y) and stores the value of X ( XNLUT) which is necessary for the linear interpolation.
