旋转泵和具有旋转泵的制动装置
摘要：
提供了一种旋转泵和具有旋转泵的制动装置。其中旋转泵包括第一侧板（71）和第二侧板（72），外转子（51）和内转子（52）设置在第一侧板（71）与第二侧板（72）之间。第二侧板具有相对于传动轴（54）与最大间隙部（53a）相邻的表面上的凹部（72d）。该凹部（72d）位于外齿通过部段（EXPS）中，该外齿通过部段（EXPS）限定在内转子的外齿部（52a）的齿尖响应于内转子的旋转所通过的线与内转子的外齿部的齿底部响应于内转子的旋转所通过的线之间。该凹部（72d）在内转子旋转时与多个间隙部中的一个间隙部连通。
摘要（英）：

A rotary pump includes a first side plate and a second side plate between which an outer rotor and an inner rotor are arranged. The second side plate has a concave portion on a surface adjacent to a maximum gap portion relative to a drive shaft. The concave portion is located in an outer teeth passing section which is defined between a line on which a teeth tip of an outer teeth part of the inner rotor passes in response to rotation of the inner rotor and a line on which a teeth bottom of the outer teeth part of the inner rotor passes in response to rotation of the inner rotor. The concave portion communicates with one of a plurality of gap portions while the inner rotor is rotated.
