Abstract
Die Erfindung betrifft eine verstellbare hydrostatische Axialkolbenmaschine mit mindestens einem - in einem Gehäuse angeordneten - mehrere Zylinder tragenden Rotor und mindestens einer schräg zum Rotor angeordneten Scheibe, auf der sich die in den Zylindern beweglichen Kolben abstützen. Hierbei wird zwischen dem Gehäuse und der zum Verstellen des Volumenstroms schwenkbaren Scheibe oder dem schwenkbaren Rotor ein aus wenigstens jeweils mindestens einem Sensorelement und mindestens einem den Meßweg darstellenden Element umfassendes, berührungsfrei arbeitendes Wegmeßsystem angeordnet. Derartige Wegmeßsysteme benötigen nur einen verschwindend kleinen Bauraum. The invention relates to an adjustable hydrostatic axial piston machine with at least one rotor arranged in a housing and carrying several cylinders and at least one disc arranged obliquely to the rotor, on which the pistons movable in the cylinders are supported. In this case, a non-contact working measuring system comprising at least one sensor element and at least one element representing the measuring path is arranged between the housing and the disc or the pivoting rotor for adjusting the volume flow. Such measuring systems only require an infinitesimally small installation space.
