Hydraulischer Wagenheber. Patentiert im Deutschen Reiche vom 15. JuK 1923 ab. Hydraulic jack. Patented in the German Empire from June 15, 1923.

Die Erfindung betrifft einen hydraulischen Wagenheber, bei welchem ein Hubzylinder, ein oder mehrere Pumpenkolben und eine Entlastungsvorrichtung zur Entleerung des Kubzylinders im Innern eines Gehäuses angeordnet sind.The invention relates to a hydraulic jack, in which a lifting cylinder, one or more pump pistons and a relief device for emptying the Cubic cylinder are arranged inside a housing.

Gegenstand der Erfindung ist eine konzentrische Ineinanderlagerung der zur Bewegung der Pumpenkolben und zur Einstellung der Entlastungsvorrichtung dienenden Wellen in einem durch eine Stopfbüchse abgedichteten Ansatz des Gehäuses.The invention relates to a concentric nesting of the movement the pump piston and shafts used to adjust the relief device in a shoulder of the housing sealed by a stuffing box.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes in zwei senkrecht zueinander steinenden Querschnitten veranschaulicht. Es bezeichnet α das Gehäuse des Wagenhebers mit Boden δ, Hubzylinder c, Zylinderkopf d und verschiebbaren Hubkolben e mit Kolbenzylinder/.In the drawing, an exemplary embodiment of the subject matter of the invention is illustrated in two cross-sections that are perpendicular to one another. It denotes α the housing of the jack with base δ, lifting cylinder c, cylinder head d and sliding piston e with piston cylinder /.

Die Pumpenkolben g und h, welche wechselweise im unteren Teü des Wagenhebers befindliche Druckflüssigkeit: in das Innere des Hubzylinders c drücken, werden durch einen gemeinsamen Hebel i betätigt, der auf einer Hohlwelle / befestigt ist. Diese ist im Gehäuseansatz m luft- und wasserdicht gelagert, Ihre Hin- und Herdrehung erfolgt durch Aufstecken eines Rohrschlüssels auf das äußere Vierkantende.The pump piston g and h, which pressure fluid located alternately in the bottom of the jack Teü: press into the interior of the lifting cylinder c, i are operated by a common lever which is / mounted on a hollow shaft. This is mounted airtight and watertight in the housing attachment m ; it is turned back and forth by attaching a pipe wrench to the outer square end.

In der Hohlwelle / ist noch eine Welle η gelagert mit äußerem Vierkant ο und innerem Sternrad oder Exzenter/?, Durch eine geringe Verdrehung der Welle η mittels eines auf ihren Vierkante aufgesteckten Rohrschlüssels verschiebt das hierdurch gedrehte Sternrad ρ einen Stößel q in seiner Achsrichtung, so* daß dieser mit seiner unteren Spitze das Entlastungsventil r öffnet.In the hollow shaft / there is also a shaft η with an outer square ο and an inner star wheel or eccentric / ?, By a slight rotation of the shaft η by means of a pipe wrench attached to its square, the star wheel ρ that is rotated thereby moves a plunger q in its axial direction, see above * that this opens the relief valve r with its lower tip.

Beide Einrichtungen, sowohl die Hubbetätigung durch die Pumpenkolben g und h als die Senk- bzw. Entlastungsvorrichtung p, q, r, sind demgemäß vollkommen innerhalb des Gehäuses α so eingebaut, daß eine Gehäusedurchdringung nur im Gehäuseansatz m erforderlich wird.Both devices, both the lifting actuation by the pump piston g and h and the lowering or relief device p, q, r, are accordingly built completely within the housing α so that a housing penetration is only required in the housing extension m.
