Abstract

The invention relates to a modular construction system for a piston machine (100), comprising at least two separate housing parts capable of being joined together into a housing (1) of the piston machine (100), a piston (15) which is configured as a swivel element, is pivotable and is able to be arranged in the housing (1), and a housing cover (7) for covering the housing (1). The piston machine (100) is in particular configured as a modular construction system, the components of which are formed by multiple segments and joined together in a horizontal and a vertical direction in each case. The invention further relates to a piston machine (100) produced using the modular construction system and to a method for producing a piston machine (100).

Abstract

The invention relates to a piston machine which comprises: a housing with a chamber with has a substantially circle sector-shaped cross-section; a pivotal piston which is designed as a pivoting element, is arranged in the housing and comprises a first working surface, wherein the housing and the piston define at least one first variable working chamber; a drive or output which is connected to the piston; and an outlet which is arranged in the working chamber for discharging a working fluid. The housing has a cooling opening in at least one housing wall, said opening leading to the chamber at least for convectively cooling a piston side opposite the first working surface by means of a coolant.
