Abstract
Axial-piston combustion engine having a rotating drum journaled in a housing and having therein a number of pistons and the usual cylinder bores, an inclined crank disc coupled with the drum, the disc being supported against the encountered gas pressures both by the customary axial thrust bearing and, according to the invention, by two consecutive, hydraulically interconnected hydrostatic axial thrust bearings fed by an oil-pressure source, wherein only the rearward one of the two bearings has a slit for controlling oil pressure, while the rearward bearing of the two constitutes a hydraulic relief for the customary bearing.
Claims11
An axial-piston combustion engine comprising, in combination, a rotating drum (3) journaled in a stationary housing (1) and provided with cylinder bores (5), an inclined crank disc (8) coupled with said drum, pistons (6) with their rods (7) being pivotally attached to said drum, said pistons being guided in said cylinder bores, wherein said crank disc is supported against the encountered gas pressures, on the one hand, on a customary axial thrust bearing (34), and on the other hand, on two consecutive, hydraulically interconnected series arranged hydrostatic axial thrust bearings (32, 33) fed by an oil-pressure source (28 to 30), only the rearward one (33) of said two thrust bearings having a control slit (16) for controlling oil pressure, and the other one (32) of said two bearings constituting a hydraulic relief for said customary bearing.
