A pivoting piston machine, comprising

• a housing,
• a first piston and a second piston arranged in the housing, the first and second pistons being pivotable away from one another and toward one another about a pivot axis,
• the first piston having a first end surface and the second piston having a second end surface,
• a working chamber for a working medium arranged between the first end surface and the second end surface, the working chamber increasing and decreasing in size in alternating fashion during pivoting of the first piston and of the second piston,
• an inlet having an inlet mouth for admission of working medium into the working chamber, and an outlet having an outlet mouth for discharge of working medium out of the working chamber, the inlet and the outlet opening into the working chamber,
• a closing element for closing and opening up one of the inlet or the outlet, the closing element having a valve disk interacting with a valve seat,
• wherein at least one of the inlet mouth and the outlet mouth is arranged within the working chamber between the first end surface and the second end surface, and wherein the valve seat and the valve disk are arranged at one of the inlet mouth or the outlet mouth.
