The invention concerns axial piston machines for installation in gearboxes and for detachable attachment thereto, having an machine housing open on one side, a connection block which closes this housing and has a pressure duct and an suction duct for the pressure medium, and a driving shaft rotatably mounted in the machine housing and the connection block, which drive shaft projects from the axial piston machine for the purpose of connection to a gear unit, the gearbox being capable of being closed by means of a gearbox cover, and having through apertures for the supply and discharge of the pressure medium to the pressure duct and suction duct. In order to increase the operating reliability of the installed axial piston machine and for the easier installation and removal thereof, the axial piston machine is provided for attachment to the gearbox cover, attachment taking place by way of the connection block, which has a contact surface which bears in the attached state against an opposing surface of the gearbox cover, the pressure duct and suction duct open at the contact surface and the through apertures formed as connecting ducts open at the opposing surface, the contact surface is formed on the axial peripheral surface of the connection block, and the end of the driving shaft on the gear unit side projects from the connection block.

Axial piston machine for installation in a gearbox

In an axial piston pump of fixed or adjustable displacement having a two-part housing, namely a housing part accommodating the pistons and a connecting part through which the pressure passage and the suction passage extend, the suction passage having a suction opening with a larger cross-section than that of the pressure passage, the connecting part can be mounted to the housing part as desired in two positions turned substantially through 180.degree. about the center axis of the axial piston engine. This construction enables the pump to be adapted to operate with either direction of displacement with little trouble and expense.
