Abstract

104,879. Claudel, C. H. March 15, 1916, [Convention date]. Regulating.-To maintain a suitable compression at all speeds, (1) the normal admission valve may be controlled conjointly with a throttle valve in the inlet pipe, so that as the throttle opens, the closing of the admission valve is delayed to permit a portion of the charge to be rejected during the compression stroke, (2) the normal exhaust valve may work in conjunction with a throttle valve in the exhaust pipe, so that as the throttle valve closes, the period during which the exhaust valve is held open is reduced, thus retaining more or less of the combustion gases in the cylinder, (3) the methods described in (1) and (2) above may be combined, the throttle valves in the inlet and exhaust pipes being connected together to move in unison, or (4) a throttle valve may be located in the exhaust pipe to restrict the outlet passage more at less at low speeds. In the arrangement shown in Fig. 1. throttle valves 2, 9 in the inlet and exhaust pipes respectively are connected together by a rod 12. Connected to the links 13 for controlling the throttle valves are distance-pieces 4, 7, which are inserted between the stems of the inlet and exhaust valves and their actuating-cams to vary the timing. A pipe 14 conveys combustion gases to a carburettor or vaporiser.
