摘要： A tubephragm pump includes a tubephragm that has a pump head portion that forms a pump chamber, a driving head that holds the tubephragm and expands and contracts the pump chamber by directly pressing and pulling the pump head portion in a direction intersecting with a transfer direction of a transfer fluid, a driving unit that drives the driving head back and forth in a driving direction to expand and contract the pump chamber, and a control unit that controls the driving unit. The tubephragm is in a flat shape with a cross-sectional shape intersecting with the transfer direction of the transfer fluid of the pump chamber having a length in a direction intersecting with the driving direction longer than a length in the driving direction. A pair of liquid contacting surfaces opposing in the driving direction of the pump chamber move while maintaining a parallel state.

摘要： It is sought to provide a spool valve arrangement, which can solve such problem as leaks of a pressure medium which may occur in the case of using synthetic resin for forming various spool valve component parts, can be manufactured at low cost, is richly durable and readily permits spool valve operation rate increase. A cylinder is fitted by clearance fit in a cylinder bore in a housing. Each socket is inserted through each first pressure medium port in the housing and each second pressure medium port in the cylinder. The socket has a small diameter part, which is fitted by clearance fit in the second pressure medium port, and a large diameter part, which is engaged with a shoulder formed in the first pressure medium port. By screwing a conduit end in the first pressure medium port, the socket is held in the mounted position, thus providing a seal of the region of this port and also providing an anti-rotation effect on the cylinder relative to the housing.

摘要： The present invention is to provide a dual reciprocating bellows pump which can facilitate size reduction design of the whole pump, permit pump manufacture at low cost, and permit reducing the dead spaces in pumping chambers to provide improved self-suction performance. Valve cases of suction side and discharge side valve units are disposed one below the other along a longitudinal axis passing through the center of the cross-section of the bellows such that they project into the associated pumping chambers, and a pair of interlock shafts are disposed at positions spaced apart to the left and right from the center in the transversal direction. With this construction, it is possible to reduce the dead spaces in the pumping chambers, reduce the longitudinal and transversal dimensions of the pump and facilitate size reduction design of the pump.

摘要： A rear thrust bearing member is disposed to be in frictional contact with an axial end face of a spindle supported in a cantilever fashion in the neighborhood of and on the rear side of an impeller. Frictional heat that is generated in this part is satisfactorily diffused with a cooling effect provided by the rotation of the impeller in the pump casing and a heat diffusion effect provided by the circulating effect. Thus, a temperature rise of the frictional portions is suppressed, and adverse effects of heat on the surrounding member are prevented.

摘要： In a bellows pump, a bellows is vertically located and has an upper and a lower end sections. The upper end section is inserted in a mounting through hole of an upper frame portion. It is detachably mounted in the frame portion by engagement between projections and communicates with a pump head. The lower end section is detachably mounted by engagement between projections in an upper connecting end portion of a reciprocating member. A torque from a motor is received by a motion conversion mechanism including an eccentric cam member and a reciprocating member, and causes elongation and contraction of the bellows in vertical direction. A motor shaft is loosely engaged with the eccentric cam member, which is supported by a pin shaft and extends along a horizontal axis of the motor shaft.
