The inner ring has a cylinder, an insert, and outer and inner protrusions. The union nut has a body and a pressing member. The inner sleeve has a through hole serving as a channel. The inner protrusion extends from the cylinder to an axial direction to contact the inner sleeve. The inner protrusion has a through hole serving as another channel connected with the inner sleeve's channel. The tip of the inner protrusion has an inner diameter not less than the minimum inner diameter of the inner sleeve. An inner peripheral surface is located at the inner periphery of the inner protrusion and causes it to reduce in inner diameter toward another axial direction.

摘要： A resin-made pipe joint is provided in which, after a coupled tube is detached, the tube can be recoupled surely and easily, and the sealing property between a joint body and a sleeve can be satisfactorily maintained even in the initial coupling of the tube, and also even in the recoupling of the tube.
The joint body 3 and the sleeve 4 are produced by using a fluorine resin. A sealing portion 31 which seals between the inner circumferential surface of an inserting portion of the sleeve and the outer circumferential surface of the inner cylinder portion is formed by press-inserting the inserting portion 27 into a groove portion 20 of the joint body. When, with respect to the inserting portion and the groove portion, an insertion rate of the inserting portion to the groove portion is indicated by X, and a multiplying factor of the radial width of the inserting portion to the radial width of the groove portion is indicated by Y, the resin-made pipe joint has the insertion rate and multiplying factor which are within a range that is defined by following Expressions (1) and (2): (1) Y = -0.218X + 1.218 and (2) Y = -0.67X + 1.67.

摘要： Provided is a bellows pump device that is able to reduce fall of a discharge pressure of a transport fluid during contraction operation of a bellows. The bellows pump device (BP) supplies pressurized air to a hermetic discharge-side air chamber (21) thereby to cause a bellows (13, 14) disposed within the discharge-side air chamber (21) to perform contraction operation to discharge a transport fluid, and discharges the pressurized air from the discharge-side air chamber (21) thereby to cause the bellows (13, 14) to perform expansion operation to suck the transport fluid. The bellows pump device (BP) comprises an electropneumatic regulator (51, 52) configured to adjust an air pressure of the pressurized air to be supplied to the discharge-side air chamber (21), such that the air pressure is increased so as to correspond to a contraction characteristic of the bellows (13, 14) during the contraction operation of the bellows (13, 14).
