Document Type and Number:
WIPO Patent Application WO2000031448
Kind Code:
A8
Abstract:
A shock wave generator (10) is provided incorporating a compressed gas reservoir (20), a high speed valve assembly (30), and a shock tube (50). The high speed valve assembly (30) is arranged to open and close selectively a gas passage (22) extending from the compressed gas reservoir (20) to the shock tube (50). The high speed valve assembly (30) comprises a valve sleeve(32) , a valve seat (34), and a valve sleeve driving assembly (40). The valve sleeve (32) is arranged to extend across the gas passage (22) between a first side (24) of the gas passage (22) and a second side (26) of the gas passage (22). The valve seat (34) is arranged on the second side (26) of the gas passage (22) and is positioned to receive the valve sleeve (32) upon extension of the valve sleeve (32) across the gas passage (22). The valve sleeve driving assembly (32) is arranged to cause extension and retraction of the valve sleeve (32) across the gas passage (22).
