Abstract
1421840 Percussive tools IMPULSE PRODUCTS CORP 29 June 1973 [10 Aug 1972] 24111/75 Divided out of 1421839 Heading B4C [Also in Division F2] The subject-matter of this Specification is identical with that described in Specification 1,421,839, but the claims are concerned with a valving means for controlling fluid flow through a passageway, such as between a charging chamber (72) and a triggering chamber (36) Figs. 1 to 3 and 7 to 9 (not shown), comprising a valving element having a piston (18) on one end and a probe (38) on the other, the piston and probe having sealing surfaces which cooperate with portions (28, 40) of the passageway to control the fluid flow therethrough, and a poppet valve (48) which slidably engages the probe and is closed at one end.
