Title: Hydraulic metering mode transition technique for velocity based control system
Inventor: PFAFF JOSEPH L
IPC: F15B11/16
Filed: 2007-04-02
Abstract: <P>PROBLEM TO BE SOLVED: To solve the problem of a drastic limitation on efficiency derived from having a plurality of metering modes.  <P>SOLUTION: The flow of a fluid to a hydraulic actuator is controlled by a valve assembly operated in different metering modes at various points in time for energy conservation. The metering mode to use is selected in response to the hydraulic load applied to the hydraulic actuator. Specifically, the present magnitude of hydraulic load is determined and compared with first and second thresholds. Below the first threshold, only a first metering mode is activated, and only a second metering mode is activated above the second threshold. A combination of the first and second metering modes is used when the hydraulic load is between those thresholds, wherein the metering modes are used in proportion to a proportional relationship of the hydraulic load to the first and second thresholds. The use of a metering mode combination in this manner smoothes transitions between the first and second metering modes.  <P>COPYRIGHT: (C)2008,JPO&INPIT
