Hydraulic gear pump or motor for refuse compacting unit - has engaging roller gears axially movable w.r.t. each other, and radially directed seal mechanism

摘要

The hydraulic gear pump, e.g. for a refuse compacting unit, has axially slidable adjustable inter engaging gears. An arc shaped seal mechanism, has a radial directed sealing surface. A first gear wheel (1) is axially slidable on spindle (10). A second gear wheel (2) engages gear wheel (1) and is rigid fixed to spindle (12). Both rollers fit inside a housing (3). Teeth tops of roller gear contact an arc profile of seal (4). Stop element (5) contacts roller gear (1). A spindle (10) is sidable in a rotary and sliding bearing (14).
