Bei den im Viertakt arbeitenden Gasmaschinen, namentlich bei gröfseren, ist für die Eröffnung des Auslafsventils wegen der dabei noch herrschenden beträchtlichen Endspannung im Cylinder ein ziemlicher Arbeitsaufwand erforderlich. Die vorliegende Neuerung bezweckt, denselben und die damit zusammenhängenden Uebelstände zu vermeiden. Es sind dazu zwei Auslafsventile von verhältnifsmäfsig kleinen Dimensionen angeordnet, F1 und V2. Das erste steht wie gewöhnlich mit dem Compressionsraum in Verbindung, das letztere ist mit seinem in den Cylinder führenden Kanal so angeordnet, dafs der Kanal während des gröfsten Theiles des Hubes vom Kolben verdeckt bleibt und erst gegen Ende Hub frei wird. Die Eröffnung von V2 erfolgt während des Explosionshubes, ehe der Kanal freiliegt, also ehe ein Druck darauf wirkt. Die Eröffnung von V1 erfolgt, wenn der Kolben den Auslafshub beginnt, der Druck im Cylinder also bereits nachgelassen hat.In the four-stroke gas engines, especially the larger ones, a considerable amount of work is required to open the outlet valve because of the considerable final tension that still prevails in the cylinder. The present innovation aims to avoid the same and the evils connected with it. For this purpose, two outlet valves of relatively small dimensions are arranged, F 1 and V 2 . The first is connected, as usual, with the compression chamber; the latter, with its channel leading into the cylinder, is arranged in such a way that the channel remains covered by the piston during the greater part of the stroke and only becomes free towards the end of the stroke. The opening of V 2 takes place during the explosion stroke, before the channel is exposed, i.e. before pressure acts on it. The opening of V 1 takes place when the piston begins the exhaust stroke, i.e. the pressure in the cylinder has already decreased.
Der Abschlufs von F2 erfolgt, nachdem der Kolben den Kanal wieder überschritten hat, der Abschlufs von F1 gegen Ende des Auslafshubes. Die Bethätigung der Ventile geschieht in bekannter Weise.The conclusion of F 2 takes place after the piston has crossed the channel again, the conclusion of F 1 towards the end of the exhaust stroke. The valves are actuated in a known manner.
