Title: Spool valve structure
Inventor: HIDAKA YUICHI
IPC: F16K3/26
Filed: 2000-06-05
Abstract: PROBLEM TO BE SOLVED: To compose a spool valve for switching a control oil pressure to an open drain circuit to be compact and light weight at a low cost. SOLUTION: This spool valve 1 comprises a spool 39 slidably disposed in a spool housing 11. An oil groove 41 on a ring is formed in an outer circumference of the spool 30. This oil groove 41 is opened at a spool end part through a through oil way 42 perpendicular to the spool 30 and through oil ways 43 and 44 axially penetrating the spool 30, and it is communicated with a drain line 43 at the open end part. As a signal pressure is applied to a signal line 21 of the spool valve 1, the spool 30 slides to move to the left to communicate a control line 22 with the oil grove 41. At this time, the control oil pressure of the control line 22 goes through the oil way 42 to be jetted from the through oil way 43, thereby additive thrust is applied to the spool 30.

IPC: F04D15/00
Filed: 2000-06-29
Abstract: PROBLEM TO BE SOLVED: To select a variable speed water supply system performing delivery pressure constant control and estimation terminal pressure constant control so that a motor can show its capacity 100%. SOLUTION: A requested specification is made to be a point P1 (flow rate Q1, head H1). At first, a number of revolution N' required for the pump to satisfy P1 is obtained. The number of revolution N' is obtained by assuming a quadric curve S passing the origin and a point P, finding a flow rate Q1' of a point P1' crossing a characteristic curve of the pump when the quadric curve S is at a number of revolution N, and multiplying N by a ratio of the flow rate (Q1/Q1'). Next, a required power L1 at the flow rate Q1 is obtained when the pump is operated with the number of revolution N'. The required power L1 is obtained by multiplying a required power L1' at the flow rate Q1' at the number of revolution N by (N1'/N1)3 because the required power is proportional to cube of the ratio of the number of revolution.  The pump can be operated with the number of revolution N1' if the obtained L1 does not exceed a rated output Llim of the motor.
