摘要： A rapid-discharge-valve structural body (2) allows air to flow from an input-side space (9A) to an output-side space (9B) in accordance with the flow rate of air to be supplied to a supply passage (101). Accordingly, the flow rate of air to be discharged from a discharge passage (113) also changes. As a consequence, flow rate peaking can be prevented.

摘要： A diaphragm pump includes a quick discharge valve unit that comprises a vessel including a supply passage, a check valve seat, a delivery passage and a discharge passage, and an elastic member configured to partition an internal space of the vessel into an input-side space connected to the supply passage and an output-side space connected to the delivery passage and the discharge passage. The elastic member includes a check valve body to prevent an inflow of air from the output-side space to the input-side space, and a discharge port valve body configured to close the discharge passage when air is supplied to the input-side space through the supply passage. The vessel includes a connecting path having a sectional area smaller than an area of a section of the supply passage, and configured to release pressurized air in the input-side space to an outside.

摘要： A diaphragm pump (1) includes a driving body (33) configured to convert a rotation of a crank body (31) into a reciprocal motion and transmit the reciprocal motion to a deformed portion (11) of a diaphragm (7). The driving body (33) includes a shaft portion (36) including a shaft hole (43) in which a driving shaft (32) fixed to the crank body is rotatably fitted. The shaft hole is a non-through hole including an opening-side end (43a) and a closed-side end (43b) each including an inner peripheral surface that contacts the driving shaft over a whole circumference. The shaft portion includes an oil storage (44) opening to a region between the opening-side end and the closed-side end of the shaft hole.
