PURPOSE:To make both functions of filtering and air bleeding to be compatible by forming an air vent hole for interconnecting a pressurized chamber to an upper chamber, in a partition member, and enabling this air vent hole to be closed by a closing member retractable from the outside, in a reservoir equipped with a filter. CONSTITUTION:In a reservoir provided with a filter 26 in a reservoir body having both inflow and outflow ports 15, 16, there is provided a partition member 20 which partitions the inside of the the reservoir body 10 into upper and lower chambers 17, 18 between these inflow and outflow ports 15, 16. Then, a pressurized chamber 22 is formed in space between a recess opening to the lower side formed by projecting a part of this partition member 20 to the upper part and the filter 26. In addition, a protuberant part 21 having a straightening part 23 gently taking in a work fluid flowing into the pressurized chamber 22 from the inflow port 15 and an opening 24 interconnecting these upper and lower chambers 17, 18 via the filter 26 are formed in this partition member 20. In this case, an air vent hole 25 for interconnecting the pressurized chamber 22 to the upper chamber 17 is formed in this protuberant part 21, and this air vent hole 25 can be closed by a closing member 42. |
