Emergency air shutdown system for a diesel engine
First Claim
1. An emergency air shutdown system for a diesel engine wherein said engine has an air intake manifold and a plurality of discharge tubes for delivery of air from an air inlet into said manifold, said system comprising:
- a valve member for each discharge tube;
means mounting each said valve member for movement perpendicular to the flow of air through said associated discharge tube between an open position, externally of said associated discharge tube and outside the path of air flow therethrough, and a closed position extending across said tube to block the flow of air therethrough;
locking means normally retaining each said valve member in said open position; and
activating means for each said valve member operative to advance said valve member from its normally open position to said closed position.

Abstract
An emergency air shutdown system for diesel engines which has air intake manifold and curved discharge tubes leading into the manifold for a plurality of cylinders, the system comprising a valve member for each discharge tube and pivotal mounting means therefor to cause movement of the valve member about an axis substantially parallel to the air flow through the discharge tube between an open position outside the path of air flow and a closed position across the tube to block the air flow. Locking means are provided for keeping the valve in an open position, and activating means are provided to effect release of the locking means so as to permit rapid movement to the closed position across each tube.

8. In an emergency air shutdown system for a diesel engine wherein said engine has an air intake manifold and curved discharge tubes to deliver air into said manifold, said system comprising:
-
a closure plate for each discharge tube, each said closure plate being of a circular configuration conforming to the cross-sectional configuration of each associated discharge tube and provided with sealing means to form a seal between said closure plate and said tube in the closed position; means pivotally mounting each said closure plate externally of its associated discharge tube for movement about an axis parallel to the flow of air through an annular recess in the wall of said associated discharge tube between an open position outside the path of air flow and a closed position extending across said tube to block the flow of air therethrough; releasable locking means retaining each said closure plate in an open position; and activating means for each said plate operative to release said locking means whereby to pivot said closure plate from its normally open position to said closed position. - View Dependent Claims (9, 10, 11, 12, 13)
