Hydrostatic piston engine

A hydrostatic piston engine, comprising:

• a housing;
• a high-pressure chamber operably connected to the housing;
• a low pressure chamber operably connected to the housing;
• a cylinder drum mounted rotatably within the housing and defining a plurality of cylinder bores, each cylinder bore receiving a corresponding working piston of a plurality of working pistons in a longitudinally displaceable manner;
• a control plate supported by the housing and defining at least one low-pressure opening, at least one high-pressure opening, and a reversing surface,
• wherein each cylinder bore and each corresponding working piston defines a corresponding hydrostatic working chamber of a plurality of hydrostatic working chambers,
• wherein each hydrostatic working chamber has a corresponding opening of a plurality of openings on an outer surface of the cylinder drum,
• wherein when the cylinder drum rotates in a rotational direction, each corresponding opening is fluidly coupled to (i) the high-pressure chamber through the at least one high-pressure opening, (ii) the low-pressure chamber through the at least one low-pressure opening, or (iii) the reversing surface which is located between the at least one high-pressure opening and the at least one low pressure opening in the rotational direction,
• wherein at least one pressurizing medium comprises at least one opening in and extending from the reversing surface to a pressurizing medium trough,
• wherein the at least one pressurizing medium channel has a first portion along which a flow cross section increases in a flow direction from the reversing surface towards the pressurizing medium trough,
• wherein the reversing surface completely defines a periphery of the least one opening, and
• wherein the at least one pressurizing medium channel extends completely through the control plate in an axial direction perpendicular to the rotational direction.
