ABSTRACT:
A fluidic device senses acceleration of a vehicle or the like and may control a fluid motor or other mechanism which is to be actuated in response to acceleration. A nozzle directs a jet of fluid across an open gap in a direction transverse to the direction along which acceleration is to be sensed. Two receiver ports are positioned to receive and divide the fluid jet in the absence of flow deflection. Upon acceleration of the device, inertial effects cause the jet flow to be slightly deflected thereby changing the amount of flow received at one receiver port relative to the other to produce a fluidic signal. The signal may be amplified and caused to actuate a fluid motor. Compensating means are provided to eliminate signal error which might otherwise arise from tilting of the device or from changes in jet fluid viscosity.
