Title:
MEASURING DEVICE FOR SUCTION AIR FLOW RATE
Document Type and Number:
Japanese Patent JPS56108911
Kind Code:
A
Abstract:

PURPOSE: To measure an accurate suction air flow rate while preventing turbulence by providing a hot-wire resistor and temperature compensating resistor in an air guide member.

CONSTITUTION: In the inside of the cylinder of air guide member 61 formed cylindrically to form air flow meter 6, hot-wire resistor 64 and temperature compensating resistor 65 are provided closely in parallel with a step. This air guide member 61 is to staighten turbulence passed through an air cleaner. In this supporting member 62, lead wire 7 connected to both resistors 64 and 65 is provided. An electronic circuit is connected to this lead wire 67. In addition, this air flow meter 6 is fitted detachably to throttle chamber 1 with bolt 8.
