Filed:
Feb 2, 1990
Appl. No.:
7/473871
Inventors:
John J. Lacey - Minnetonka MN
Assignee:
Fluidyne Engineering Corporation - Minneapolis MN
International Classification:
G01M 900
US Classification:
73 12
Abstract:
A free piston shock tube/tunnel having a mechanism for increasing the holding time, without correspondingly increasing viscous losses in which the shock tube/tunnel includes a diaphragm positioned in the area of connection between the compression tube and the shock tube and a selectively replaceable orifice insert positioned near the diaphragm in which the orifice insert has an opening with a diameter less than the internal diameter of the shock tube.

International Classification:
G01M 900
US Classification:
73147
Abstract:
A free piston shock tube/tunnel having a mechanism for stopping the piston or controlling the movement of the piston near the diaphragm end of the compression tube. The mechanism includes a generally annular protrusion positioned at the diaphragm end of the compression tube and extending upstream from the diaphragm to engage the piston at a point where the velocity of the piston is substantially at a minimum. The annular protrusion is spaced inwardly from the compression tube and has an inner diameter greater than the diameter of the shock tube.
