电液一体型液压装置
摘要：
电油一体型马达（1）具备油压马达（10）和电动机（30）。电油一体型马达（1）具有旋转轴（11），利用所提供的工作油使旋转轴（11）旋转。电动机（30）具有与旋转轴（11）连接的转子（32）、配置于转子（32）的周围的定子（33）、以及容纳这些构件的外壳（34）。转子（32）与外壳（34）在油压马达（10）的壳体（17）的外围被覆着配置。外壳（34）具有容纳旋转轴（11）的旋转轴收容空间（51）、以及收容定子的定子收容空间（52），在外壳（34）内设置隔离这两个收容空间（51、52）的密封构件（39）。
摘要（英）：

Disclosed is an integrated electro-hydraulic motor (1) provided with a hydraulic motor (10) and an electric motor (30). Said integrated electro-hydraulic motor (1) has a rotary shaft (11) rotated by a supplied hydraulic oil. The electric motor (30) has: a rotor (32) connected to the rotary shaft (11); a stator (33) laid out around the rotor (32); and a housing (34) containing said parts. The rotor (32) and the housing (34) are arranged so as to enclose the casing (17) of the hydraulic motor (10). The housing (34) has: a rotary-shaft-containing space (51) that contains the rotary shaft (11); and a stator-containing space (52) that contains the stator. A sealing member (39) that separates said spaces (51 and 52) from each other is provided inside the housing (34).
