Description
Leerlaufvorrichtung für Drehkolbengebläse unter Verwendung eines unter regelbarem Federdruck stehenden Ventils. Gegenstand der Erfindung ist eine Leerlaufvorrichtung für Drehkolbengebläse unter Verwendung eines unter regelbarem Federdruck stehenden Ventils. --Die Zeichnung stellt die Erfindung in einem Längs- und einem Querschnitt dar.Idling device for positive displacement blowers using an under adjustable spring pressure standing valve. The invention relates to an idling device for positive displacement blowers using a spring pressure that can be regulated Valve. --The drawing shows the invention in a longitudinal and a cross-section represent.
b ist eine auf dem Drehkolbengebläse angeordnete Haube, die durch eine Wand f (Abb. a) in Eden links gelegenen Druckraum und den rechts gelegenen Saugraum .getrennt ist. Die Stellspindel c ist in der Wandung des Saugraums mittels Kegelflächen n abgedichtet, die durch die Feder i aneinandergedrückt werden. Das Ventil g sitzt mittels Vierkants lose auf der Ventilspindel h und ist durch die Feder L belastet, die sich gegen die Mutter in legt. Letztere wird bei Drehung der Stehspindel c durch einen Mitnehmer y achsial auf der Ventilspindel h bewegt, wodurch das Ventil g mehr oder weniger stark auf seinen Sitz gedrückt wird. Wird der Druck im Druckraum aus irgendwelchen Gründen zu groß, so öffnet sich das Ventil und stellt eine Verbindung nach dem Saugraum her, so daß die Maschine leerläuft.b is a hood arranged on the rotary piston blower, which passes through a wall f (Fig. a) in Eden on the left and the pressure room on the right Is .separated. The adjusting spindle c is in the wall of the suction chamber by means Sealed conical surfaces n, which are pressed together by the spring i. That Valve g sits loosely on the valve spindle h by means of a square and is through the Loaded spring L, which lies against the mother in. The latter is turned on when the The standing spindle c is moved axially on the valve spindle h by a driver y, as a result of which the valve g is pressed more or less strongly on its seat. Will the pressure Too large in the pressure chamber for some reason, the valve opens and adjusts a connection to the suction chamber so that the machine runs empty.
