Embodiment Construction

[0027] figure 1 The axial piston machine according to the invention is shown in longitudinal section with its housing 1 in which the drive shaft 2 is supported and the cylinder drum 4 is arranged in a rotationally fixed manner on the outer circumference of the drive shaft . Pistons 6 distributed over the circumference in cylinder drum 4 are axially guided in corresponding cylinders 8 . A piston foot is formed on the end section of the piston 6 protruding from the cylinder 8 , on which a piston seat 10 is rotatably mounted, which is opposite The drive shaft 2 is slidably guided on a swash plate 12 which is inclined.

[0028] During operation of cylinder drum 4 , cylinder piston 6 is moved out of cylinder 8 and back into it as a function of the tilted position of swash plate 12 . Thus, for example in the case of an axial piston machine, the displacement volume per revolution and thus the rotational speed of the drive shaft 2 serving as output shaft can be adjusted. To adjust...

Abstract

A hydrostatic axial plunger machine is disclosed, in which a regulating pressure cylinder is constructed obliquely to a drive shaft in a casing of the hydrostatic axial plunger machine, and a regulating valve of a sleeve structure is installed in the casing. in the regulating pressure cylinder. In order to enable a maximum movement of the regulating piston in the direction of the regulating valve, the sleeve is designed to be shortened. For this purpose, the regulating pressure connection and the regulating pressure channel are arranged completely inside the sleeve, wherein the regulating pressure connection is arranged between the high-pressure connection and the low-pressure connection.

Description

technical field [0001] The invention relates to an axial piston machine according to the preamble of patent claim 1 . Background technique [0002] In document RD98714 of April 2015 the applicant discloses a hydrostatic axial piston motor which is used as a fan motor. Due to its rotatability, it is possible to reverse the direction of rotation of the output shaft of the fan motor and thus of the fan impeller while the flow direction of the pressure medium remains the same. This serves to blow dirt out of the ventilation device. The fan motor has an electro-proportional (EP) adjustment of the swivel angle (Schwenkwinkel) and thus an electro-proportional adjustment of the rotational speed of the driven shaft. The regulating valve and the associated lifting magnet are arranged, for example, at 90° relative to the longitudinal axis of the housing or relative to the output shaft of the fan motor. [0003] Furthermore, axial piston machines with a rotatable swash plate and with...
