Abstract: A cylinder includes a cylindrical portion, an insertion portion, and a first sealing portion. The cylindrical portion has a central axis, extends in an axial direction along the central axis, and allows liquid to flow. The insertion portion extends along the central axis and is inserted into the inside of the cylindrical portion. The first sealing portion seals a space between the cylindrical portion and the insertion portion. The insertion portion includes a recessed portion and a second sealing portion. The recessed portion is annular. The recessed portion is located along an outer peripheral surface of the insertion portion and accommodates the first sealing portion. A second sealing portion seals a space between a step on a bottom surface of the recessed portion and the first sealing portion.

IPC: F25B41/40
Abstract: A liquid feeder switches a flow path of a liquid having flowed in from an inflow port to one of a flow path communicating with a first base communication port and a bypass outflow path. When a pump is attached to a base, the bypass outflow path is closed to allow the liquid having flowed in from the inflow port to flow to the pump. When the pump is removed from the base, the bypass outflow path is opened to allow the liquid having flowed in from the inflow port to flow from the bypass outflow path to the outflow port. The liquid feeder is able to prevent liquid leakage when a pump of a liquid feeder is replaced or repaired.

Abstract: A stator assembly includes a stator that drives a rotor that is rotatable about a central axis extending in a vertical direction, a stator support that supports the stator, and a filling portion that covers the stator. A first radial end portion of the stator is fixed to a second radial side surface of the stator support. An insulator of the stator includes an upper insulator covering an upper surface of a stator core. A first radial end portion of the upper insulator contacts the second radial side surface of the tubular stator support extending in an axial direction. An annular insulator concave portion that is recessed to the axial upper side is provided in the first radial end portion of the upper insulator. A first space, surrounded by the insulator concave portion, the stator core, and the stator support, is filled with a filling material.
