Starting and pressing braking device for internal combustión drive machines. (Machine-translation by Google Translate, not legally binding)

摘要

An internal-combustion engine having a compressed air starting and braking system incorporates a compressed air container 4 connected through a main starting valve 3 to a main starting air conduit 6 to which the or each cylinder is connected through a piston controlled starting valve 7 the control piston of which is arranged to be operated by air from the main conduit through an engine driven control member 9. A subsidiary starting air conduit 12 is connected between the main conduit and the or each control member and is provided with means 15 for throttling the flow of starting air therethrough and means 12a for permitting braking air to flow to the or each control member at the pressure obtaining in the main conduit. The pressure surface of the control piston of the or each starting valve has an area which is so much greater than that of the effective pressure surface of the associated starting valve head that during braking the or each starting valve remains open for a period of time which is pre-set by its control member which is independent of the compression pressure in its cylinder. The shut-off valve 16 is adapted to be opened manually or by means of an automatic device when braking.
