摘要：往復動ピストンは円柱状本体と少なくとも２個の離間したリングシールとを含む。円柱状本体は中空シリンダ内において往復動可能とされるとともに、リングシールは円柱状本体の周囲に配置される。円柱状本体内には除去装置が設けられる。除去装置は内室と一方向流体通路を含む。内室は離間するリングシールの間の空間と流体接続する。内室内の流体圧がシリンダ室内の流体圧よりも大きい時に、一方向流体通路は内室からシリンダ室への一方向の流体流通を許容する。流体除去方法は、ピストンシールから漏出した流体を収集する工程と、収集した流体をピストン内に配置された除去装置を介して元のシリンダ室へ戻す工程とを含む。

摘要： PROBLEM TO BE SOLVED: To obtain a reliable high pressure fuel pump device at a low cost which can improve the durability of the metal bellows for a fuel seal for preventing the leak of the fuel leaked from the gap between a sleeve and piston to the outside. SOLUTION: In this device, the drain passage 12 of a leaked fuel in the metal bellows 26 for a fuel seal is merged with the drain passage 13 of a high pressure fuel regulator 8. Further, a lead type check valve 17 is provided on the upper streamside on the drain passage 12 between this junction 14 and the metal bellows 26 for fuel seal and a ball type check valve 18 is provided on the lower streamside.

摘要： PURPOSE: To avoid shutting off of an engine during flight by preventing mixing of hydraulic fluid and blocking of a drain and providing a shaft seal system between a pump and a gear box. CONSTITUTION: An arclike chamber 56 is formed in a flangelike end member 22 of a pump, which has an annular shoulder 58 receiving a baffle 60 having a plate shape. The baffle 60 is engaged with a seal 62 arranged in a groove 64 provided in the end member 22 of the pump. The baffle 60 has a plurality of grooves 68 in the radial direction on its flat face, which form a passage P when they are arranged on the end member 22. When hydraulic fluid leaks across an inner seal 52, leaking hydraulic fluid passes the passage P formed by this groove and enters the arclike chamber 56. The hydraulic fluid collected in the chamber 56 is discharged out of an aircraft through a drip drain system of the aircraft. Consequently, it is possible to prevent mixing of hydraulic fluid which leaks across a seal of the pump and a gear box and has no interchangeability.

摘要： PURPOSE: To reduce an excess pressure in a drain oil chamber so as to avoid splashing loss by disposing a pump device between a drain oil port and a tank for sucking drain oil from the drain oil chamber of a motor. CONSTITUTION: A fluid flow from a hydraulic pump 1 is supplied to a nozzle 35 of a jet pump 34 through connection line 41 having a working pressure line 3 or 4 and a throttle element 42, a shuttle valve 40 and a working medium line 39. When the flow is discharged from the nozzle 35 at a high speed, a negative pressure is generated at an inlet portion of the jet pump. When this negative pressure reaches a value sufficiently overcoming a flow drag in a channel between a hydraulic motor 25 and a tank 9, drain oil is sucked from a drain oil chamber of the hydraulic motor 25 through a drain oil port 30. Kinetic energy of the sucked drain oil is converted into pressure energy for transferring the drain oil to the tank 9 through a drain oil line 38. Consequently, due to the suction of the jet pump 34, a liquid level in the drain oil chamber becomes lower than a level of a rotation driving mechanism, thus avoiding loss caused by splashing.

摘要： PURPOSE:To obtain the reciprocating pump having a high discharging pressure, a large discharging quantity and a high quantitative accuracy by a method wherein a sealed chamber is formed by providing a bellows at the driving side of a shaft sealing part slidably contacted by a reciprocating shaft. CONSTITUTION:When a plunger 25 is pushed to the side of a pump chamber 26, the bellows 33 is contracted into the axial direction thereof and the volume of the sealed chamber 36 is reduced while a gaseous body such as air or the like, which is the fluid in the sealed chamber 36, and a pump handling liquid 27 leaked from the shaft sealing part 28 are discharged to the suction side 41 of the pump from a passing port 37 through a returning pipeline 38. When the plunger 25 is retracted, the bellows 33 is extended into the axial direction thereof and the volume of the sealed chamber 36 is increased while the liquid which has been discharged to the suction side 41 of the pump is now sucked into the sealed chamber 36 from the returning pipeline 38 through the passing port 37. By repeating these operations, the pump handling liquid 27, leaked from the shaft sealing part 28 into the sealed chamber 36, is returned to the suction side 41 of the pump.
