Abstract

536,739. Valves. AKTIEBOLAGET ATLAS DIESEL. Dec. 21, 1939, No. 32701. Convention date, Jan. 12. [Class 135] In a pneumatic tool in which a valve with a sealing collar 8 co-operates with a seat and is subjected to the pneumatic pressure tending to close the valve, the valve body 9, 10 being slidable within the bore 3 of a valve housing 2 provided with control passages, the valve body being depressed by hand to open the valve, a byepass channel is provided between a point of the bore 3 situated immediately behind the seat, and that part 14 of the bore which is bounded by the remote end surface of the valve body. A byepass channel 15 may be formed in the valve body, as shown in Fig. 1, or a byepass channel 17 may be formed in the valve housing, as shown in Fig. 2.
