Axial piston machine with neutral valve integrated in the pot-like housing part

An axial piston machine comprising:

• a housing, on which a first working connection, a second working connection, a supply connection, and at least one return connection are arranged, the housing comprising a pot-like housing part and a plate-like housing part, which are fixedly connected to one another and enclose an interior;
• an axial piston pump/motor, which is in fluid exchange connection with the first and second working connection;
• a double-acting control cylinder arranged exclusively in the pot-like housing part and configured for continuous adjustment of a displacement volume of the axial piston pump/motor, the control cylinder comprising a first control chamber and a second control chamber;
• an auxiliary pump separate from the axial piston pump/motor;
• a first control assembly having a first inlet point, a first return point permanently fluidly connected to the interior of the housing, and a first outlet point permanently fluidly connected to the first control chamber;
• a second control assembly having a second inlet point, a second return point permanently fluidly connected to the interior of the housing, and a second outlet point permanently fluidly connected to the second control chamber;
• and
• a third control assembly having a third inlet point, a third return point permanently fluidly connected to an interior of the housing, and a third outlet point;
• wherein the at least one return connection opens into the interior,
• wherein a fluid flow path passes from the auxiliary pump via a transfer point, further via the third inlet point, to the third outlet point, and finally parallel to the first and second inlet points,
• wherein the first and second working connection are arranged on the plate-like housing part,
• wherein the first, second, and third control assemblies are each received on the housing, at least in sections, in a respective first, second, and third receiving bore,
• wherein the transfer point is located in the fluid flow path where the plate-like housing part contacts the pot-like housing part,
• wherein the first, second, and third receiving bores are each arranged directly in the pot-like housing part, and
• wherein a first portion of the fluid flow path arranged downstream of the transfer point, extends over its entire length directly in the pot-like housing part.
