摘要： A rolling diaphragm pump that can inhibit an increase in cost with a simple configuration is provided. A rolling diaphragm pump 1 includes: a housing 2; a piston 3 disposed so as to be slidable relative to an inner peripheral surface of the housing 2 and reciprocatable in an axial direction; a rolling diaphragm 4 having a movable portion 41 disposed at one end portion in the axial direction of the piston 3 and reciprocatable together with the piston 3, a fixed portion 42 fixed to the housing 2, and a flexible connecting portion 43 connecting the movable portion 41 and the fixed portion 42 to each other; a pump chamber 5 defined by the rolling diaphragm 4 at one side in the axial direction within the housing 2 and into and from which a transport fluid is sucked and discharged by changing a volume of an interior of the pump chamber 5 by deformation of the connecting portion 43 due to reciprocation of the piston 3; and a working fluid chamber 6 defined by another end portion in the axial direction of the piston 3 at another side in the axial direction within the housing 2 and into and from which a working fluid is supplied and discharged, thereby causing the piston 3 to reciprocate.

摘要： A gasket includes a first slope at a first axial end. The fluid device includes a second slope that contacts the first slope. The first slope and the second slope have different gradients. The first slope allows at least the first axial end to be deformed along the second slope. The first slope contacts the second slope with a gradient that varies depending on a gradient of the second slope to seal a gap between the first slope and the second slope.

摘要： A diaphragm pump includes a reciprocable diaphragm, an actuator including a motor, and a control device. The control device resets an origin of the diaphragm in a reciprocating direction, when detecting a step-out of the motor. After resetting the origin, the control device activates the actuator to move the diaphragm to the origin.

摘要： A diaphragm pump has: a housing; a piston; a shaft; a rolling diaphragm, which is configured so that a lid portion reciprocally moves integrally with the piston; a driving device, which can convert rotational movement of a motor section to linear movement, and output the linear movement from an output axle to the shaft; a guiding member; and a restricting mechanism. The guiding member is placed on another axial end side of an interior of the housing with respect to the piston, attached to the housing, and able to guide the shaft movably in the axial direction. The restricting member is disposed in the housing and between the guiding member and the shaft, and able to restrict rotation of the shaft about the axis while allowing reciprocal movement in the axial direction.

摘要： An antistatic cover which, when the cover covers an insulating resin-made tube, can enhance the certainty of preventing the tube from being electrically charged, and can facilitate attachment to and detachment from the tube. The tubular cover body, is divided in a circumferential direction to form first and second divided portions. The cover body is elastically deformed such that the first and second divided portions separate from each other, and allow the tube to pass through between the first and second divided portions. The cover body has a plurality of first cutaway portions, which pass through at least one of the first and second divided portions in a radial direction of the cover body, and is configured such that, when the cover body is fitted onto the tube, a part of the tube can be exposed through the plurality of first cutaway portions.

摘要： A structure allowing a gasket to be mounted on a fluid device is provided. The gasket includes an annular attaching portion that has a first slope at an axial end. The fluid device includes an annular attached portion with a second slope that contacts the first slope. The first slope at least partially includes a contact area that contacts the second slope to seal a gap between the first slope and the second slope. The contact area has an annular bulge protruding toward the second slope in contrast to other portions of the first slope so that the bulge is the earliest contact portion with the second slope when the contact area is brought into contact with the second slope.

摘要： A structure of a resin-made pipe joint includes a sleeve which is press-insertable from one axial side into one longitudinal end portion of a flexible tube to flare the one longitudinal end portion to hold the flared state, a joint body which is couplable to the sleeve, and a union nut which is fastenable to the joint body to hold a state where the sleeve press-inserted into the one longitudinal end portion is coupled to the joint body. The sleeve has a taper-like first outer circumferential surface, a second outer circumferential surface having an outer diameter that is smaller than a maximum outer diameter of the first outer circumferential surface, and an annular step portion which is an annular step portion that is disposed between the first outer circumferential surface and the second outer circumferential surface and comprises an edge portion on a side of the first outer circumferential surface.
