摘要： A flexible unit absorbing misalignment and transmitting torque from a driving shaft to a driven shaft is provided between a pair of flanges individually provided on each of the driving shaft side and the driven shaft side, both the driving shaft and the driven shaft being hollow. A communication passage letting hollow regions of the driving shaft and the driven shaft communicate with each other to form a circulation space for a cooling fluid is provided in the flexible unit. The flow of the cooling fluid cooling a driving source driving and rotating the driving shaft from the inside is created in the circulation space. A seal portion seals between the circulation space and an outside space to prevent leakage of the cooling fluid from the circulation space to the outside space.

摘要： A diaphragm for use in a pump includes a cover configured to contact fluid to pump the fluid and a backing disposed at least partially within the cover. The backing includes a flexible plate that extends outward relative to a core of the backing, the flexible plate configured to flex during reciprocation of the diaphragm. The cover is formed from a first polymer and the flexible plate is formed from a second polymer.

摘要： A respiratory mask includes a body having an interior space that defines a plenum between the body and a face of the user when the user is wearing the mask. The respiratory mask also includes a voice transmittal feature in and contiguous with the body that has a voice transmittal membrane that is configured to vibrate in response to sound waves generated by the user such that the voice transmittal membrane transmits the sound waves from the plenum of the body to an ambient environment of the user. The voice transmittal feature thus enhances the intelligibility of a user's speech so that others may more clearly understand what the user is saying. For example, this may increase safety and efficiency in emergency response situations in which the use of a respiratory mask is required.

摘要： Described is a method for manufacturing a diaphragm assembly through the use of injection molding. The method can avoid the use of PTFE as a chemically resistant coating. Further, the method can increase overall adherence of a polymer diaphragm to an insert through the use of an interference surface on at least the surface of a head of the insert.

摘要： A metal diaphragm damper includes disc-shaped damper main body having two diaphragms between which a gas is sealed and each of which is provided with a deformable portion at the center thereof and two regulation members that are disposed outside of the deformable portions of the two diaphragms. The metal diaphragm damper includes a first welding part provided with a first welding layer WD1 that seals an annular periphery portion of the regulation member and an outer edge portion of the diaphragm, and a second welding layer WD1 that seals an annular periphery portion of the other regulation member and an outer edge portion of the other diaphragm. The metal diaphragm damper further includes a second welding part provided with a welding layer WD2 that seals the annular periphery portions of the two regulation members.

摘要： A fluid control valve includes a cover portion and a body portion. Inner surfaces of the cover and the body portion define a chamber that includes an inlet and an outlet in communication with the chamber. The fluid control valve also includes a diaphragm disposed between the cover portion and the body portion. The diaphragm has a flexible member that is disposed within the chamber for controlling communication between the inlet and the outlet. The upper surface of the flexible member has a substantially smooth wall portion. The flexible member has an inverted position in which the upper surface conforms to at least a portion of the inner surface of the cover portion to define a passageway that permits communication between the inlet and the outlet. The diaphragm is configured such that the lower surface of the flexible member and a seat member on the body portion have corresponding radius of curvatures such that the flexible member conforms to and seals against the seat member when the flexible member is not in the inverted position.

摘要： A diaphragm for a diaphragm valve comprises a base body made from an elastomer, the base body having a side facing towards the media and a side facing away from the media. A force transmission component is disposed at the base body on the side facing away from the media for the attachment of a spindle drive for a diaphragm valve. Furthermore, the base body has a reinforcement area, the reinforcement area being disposed on the outside of the base body on the side of the base body facing away from the media.

摘要： An operating unit for a fluid-operated diaphragm actuator, the unit consisting of a drive diaphragm, two retaining elements flanking the drive diaphragm on opposite sides and an output rod extending through these components. The drive diaphragm is mounted on the output rod by being clamped between the two retaining elements with a predetermined clamping force, wherein each of the two retaining elements is fixed on the output rod by means of a welded connection. A method that is particularly suitable for producing such an operating unit and to a fluid-operated diaphragm actuator equipped with such an operating unit.
