安全阀构造体
摘要：
一种附属于泵体(10)的安全阀构造体(20)，其具有：第一排出部(31)，其在排出压力为第一规定的压力时排出油；第二排出部(32)，其在排出压力达到比第一规定的压力高的第二规定的压力时排出油；第三排出部(33)，其在排出压力超过第一规定的压力且成为第二规定的压力或成为不足第二规定的压力的压力后排出油；以及泄压孔(34)，其使阀簧(23)周围的油释放。第二排出部、第一排出部、第三排出部以及泄压孔依次设置于从导入部(29)到弹簧限制部件(24)的之间。
摘要（英）：

A relief valve structure (20) attached to a pump body (10) includes: a first discharge portion (31) for discharging oil when a discharge pressure is a first predetermined pressure; a second discharge portion (32) for discharging the oil when the discharge pressure reaches a second predetermined pressure higher than the first predetermined pressure; a third discharge portion (33) for discharging the oil when the discharge pressure exceeds the first predetermined pressure and reaches the second predetermined pressure or a pressure lower than the second predetermined pressure; and a pressure relief hole (34) for releasing the oil from an area around a valve spring (23). The second discharge portion, the first discharge portion, the third discharge portion, and the pressure release hole are provided in this order between an introduction portion (29) and a spring retaining member (24) when viewed from the introduction portion (29).
