Problems solved by technology

Large clearances in the wobble plate can cause deformation of the wobble ring due to the gas pressure to be transmitted and thus lead to wear
In addition, the adjustment behavior of the swivel plate (which is dependent on the deflection moment with respect to the tilting joint) and its unbalance due to a large play are adversely affected.

Embodiment Construction

[0044] All preferred embodiments of a compressor according to the invention comprise (not shown in the figures) a housing, a cylinder block and a cylinder head. A piston is axially reciprocatably supported in the cylinder block. The compressor is driven by means of a drive shaft 1 via a pulley. Current compressors are compressors with a variable piston stroke, wherein the piston stroke is set by a pressure difference determined by the pressures in a suction side and a transmission chamber. Depending on the magnitude of the pressure difference, the wobble plate in the form of a wobble ring 2 is displaced or deflected more or less from its vertical position. The greater the resulting deflection angle, the greater the piston stroke and a correspondingly higher pressure is produced on the discharge side of the compressor.

[0045] It is evident from FIG. 1 that the oscillating disk mechanism of a compressor according to the invention and of a preferred embodiment comprises a osc...

Abstract

The invention relates to an axial piston compressor, in particular, for motor vehicle air conditioning installations, said compressor comprising, in particular, an annular pivoting disk (2) which is rotationally driven by a drive shaft (1), the incline of said pivoting disk in relation to the drive shaft (1) being adjustable. Said pivoting disk is connected, in an articulated manner, to at least one supporting element (5) which is arranged at a distance from the drive shaft (1) in such a way that it rotates therewith, and the pistons respectively comprise a joint arrangement with which the pivoting disk (2) engages in a sliding manner. The supporting element (5) is arranged on the radially outer end of a fixed force transmission element (6) which rotates with the drive shaft (1), and on the inside thereof in an approximately radial direction. The force transmission element (6) can be rotated and / or radially displaced on the supporting element (5).

Description

technical field [0001] The invention relates to an axial piston compressor according to the preamble of claim 1 , in particular a compressor for a vehicle air conditioning system. Background technique [0002] In compressor drives there is a tendency to use in compressors increasingly larger wobble disks with variable piston strokes in the form of a wobble ring, ie an annular wobble disk. One of the tilt hinges necessary for the swinging of the disc is basically integrated in the ring-shaped swinging disc. A compressor is thus known, for example, from EP 0964997 B1, in which the reciprocating movement of the piston is effected by engaging an annular disk extending obliquely to the mechanical axis in an engaging chamber. The engagement chamber piston is arranged adjacent to the closed cavity. For a substantially play-free sliding engagement in each tilting position of the wobble plate or wobble ring, so-called sliding blocks are arranged on both sides of the spherical eleme...
