US Classification:

060/289000, 060/307000

Abstract:

A solenoid operated valve suitable for controlling flow of air for injection into the exhaust of an engine, the poppet is connected to the solenoid armature in a lost-motion connection. Upon energization, the armature achieves momentum during the lost-motion movement and imports an impulse to the poppet to ensure movement in the event of any tendency of the poppet to stick. A one-way valve prevents exhaust back pressure from opening the poppet.

Abstract:

The present invention relates generally to a tester and related methods for testing vehicular safety restraint systems, and more particularly, to testers and related methods for testing airbag suppression systems. A tester or method for testing an airbag suppression system according to the invention simulates movement of a vehicle occupant into a suppression zone by causing an occupant model to move toward the suppression zone, wherein a generally rotational motion and a generally linear motion of the occupant model are independently controllable by a positioning assembly. A control assembly according to the invention is able to identify the actual position of the occupant model at the time the suppression system detects the occupant model entering the suppression zone. This position may be used to evaluate the performance of the suppression system.
