Title:
交差軸を有する型式のアキシアルピストンポンプ
Document Type and Number:
Japanese Patent JP4943594
Kind Code:
B2
Abstract:
The cranked axis axial piston pump has a split rotor concentrically aligned containing an outer drive element (8) and an inner barrel (3). This barrel (3) contains the axially aligned pistons (6) reciprocating in chambers whose face (4) is pressed against the port plate (2) by the effect of a compression spring (11). This configuration reduces friction and allows compensation between the mating faces of the port plate and the barrel. The cranked hydraulic pump with axial pistons (6) consists of a rotating barrel (3) with a central axis (X) co-operating with a distribution port plate (2) associated with a support surface (4) set at right angles to this axis (X). The barrel (3) has a series of axial drillings (5) in which are mounted in a sliding fashion the corresponding pistons (6). A drive (8) distinct from the barrel (3) is provided to rotate about the axis (X) which ensures on one part the centring and driving of the barrel (3) about the axis of rotation (X) and on the other part the reaction for a spring (11) pushing the support surface (4) of the barrel (3) against the port plate (2).
