Abstract
443,410. Engine valve-gear. FORTUNA-WERKE SPEZIALMASCHINEN - FABRIK AKT.-GES., Cannstatt, Stuttgart, Germany. July 23, 1935, No. 20904. Convention date, July 23, 1934. Addition to 379,979. [Class 122 (ii)] [See also Groups XXIX and XXVIII] The invention of the parent Specification is modified by replacing the auxiliary piston and its associated throttle valve by two valve pistons 13, 13<1>, normally pressed by springs 28, 29, into contact with adjustable stops 15, 16. When the reversing valve 10 has been moved into an end position, so that the pressure fluid flows through the pipe 8, the valve 13 is moved to uncover the pipe 5 against the action of the spring 28, and the resistance due to liquid being forced through a port 31 into a reservoir 30. The working piston 2 is thus operated, the exhaust fluid opening a valve 24 and passing to the pipe 9. Reversal of the valve 10 causes the valve 131 to be moved to uncover the pipe 6, the valve 13 being returned to its initial position by the spring 28. During its return, liquid returns rapidly from the reservoir through a lightly loaded valve 33. If desired, the ports 31, 32 may be replaced by slots in the valves 33, 34 or their seats.
