Title: Flowmeter
Inventor: SHIRAI MAMORU
IPC: G01F1/36
Filed: 1985-09-04
Abstract: PURPOSE:To enable the accurate measurement of a flow rate in a directional control valve for changing over the flow direction of the fluid in a cylinder (SD) chamber by providing a reciprocating plunger (PR) with a valve and two valve seats opposite to each other for opening and closing a valve seat port. CONSTITUTION:A flowmeter is constituted of detectors 46 and 47 arranged in both the end portions of an SD chamber 42 wherein an oscillatory body 43 moving with a fluid is inserted and a directional control valve 48 capable of changing over the flow direction of the fluid in the SD chamber 42. Thus, the fluid introduced into a valve chamber 52 through an opening 60 flows in the SD chamber 42 via a valve seat port 55 and flow passages 63 and 58 and, while moving the oscillatory body 43, flows in the left direction as viewed in the accompanying drawing to an opening 61 via flow passages 57 and 59. On the other hand, when a detector 46 is actuated, a solenoid 65 is deenergized and a PR 51 is moved 66 to a right position as viewed in the drawing, the fluid flows in the SD chamber 42 via a valve seat port 53 and flow passages 62 and 57 and is made to flow with the oscillatory body 43 in the right direction to flow out through the opening 61 via the flow passages 58 and 59. Then, the solenoid 65 is energized in the same manner and the PR 51 is returned to a left position. The number of times of the reciprocations of the oscillatory body that such operations as described above are repeated are measured, enabling a flow rate to be measured.
