齿轮泵
摘要：
本发明的齿轮泵(1)由如下方式构成：第1泵室(P1)包括与内齿齿轮(10)及外齿齿轮(20、30)的旋转相应地将流体吸入的第1吸入空间(L1)和与内齿齿轮(10)及外齿齿轮(20、30)的旋转相应地将流体排出的第1排出空间(H1)，第2泵室(P2)包括与内齿齿轮(10)及外齿齿轮(20、30)的旋转相应地将流体吸入的第2吸入空间(L2)和与内齿齿轮(10)及外齿齿轮(20、30)的旋转相应地将流体排出的第2排出空间(H2)，第1吸入空间(L1)和第2吸入空间(L2)相对于内齿齿轮(10)的旋转中心对称地配置，并且第1排出空间(H1)和第2排出空间(H2)相对于内齿齿轮(10)的旋转中心对称地配置。
摘要（英）：

A gear pump (1) according to the present invention is configured such that a first pump chamber (P1) comprises a first intake space (L1) space into which a fluid is taken in and a first discharge space (H1) from which the fluid is discharged, in accordance with rotation of an internal gear (10) and external gears (20, 30), a second pump chamber (P2) comprises a second intake space (L2) into which the fluid is taken in and a second discharge space (H2) from which the fluid is discharged, in accordance with rotation of the internal gear (10) and the external gears (20, 30), the first intake space (L1) and the second intake space (L2) are provided to be symmetrical about a rotational center of the internal gear (10), and the first discharge space (H1) and the second discharge space (H2) are provided to be symmetrical about the rotational center of the internal gear (10).
