<p>1508443 Measuring fluid-flows ROBERT BOSCH GmbH 21 March 1975 [29 March 1974] 47385/77 Divided out of 1508442 Heading G1R [Also in Division F1] The air-flow measuring element is deflected both by force due to pressure differential on blade 24 and aerodynamic force on element 22 the proportions of the respective forces varying dependent on displacement. As shown in Fig. 2, linkage 26, 23 maintains element 25 at a fixed angle of attack dependent on the position of pivot 28 which may be moved in response to air density or exhaust gas composition. Fuel metering may be performed in the central spindle by the overlap of apertures 32, 11 and a recess 34, receives the spread of the cone of sprayed fuel there-in.</p> |
