摘要： A foil bearing (40) includes foils (42) at a plurality of portions in a rotation direction of a shaft member (11). A top foil portion (Tf) including a bearing surface (S2) is formed in a region including a front end (421) of each of the foils (42), and a back foil portion (Bf) is formed in a region including a rear end (422) of each of the foils (42). A gap (C1) is secured between, of two of the foils adjacent to the foil (42) in a rotation direction (R) and a direction opposite to the rotation direction, the rear end (422) of the foil on the rotation direction side and the front end (421) of the foil on the side opposite to the rotation direction side. A width of the gap (C1) is set to be non-uniform in a direction (N) orthogonal to the rotation direction.

摘要： A foil bearing includes an outer member (11), and a plurality of foils (13) that are mounted to an inner circumferential surface (11a) of the outer member (11) and directly face the inner circumferential surface (11a) of the outer member (11) in a radial direction without interposition of another member (such as back foils). The foils (13) each include: holding portions (13a, 13b) that are formed at both circumferential ends and held while in contact with the outer member (11); and a body portion (13c) that is formed circumferentially between the holding portions (13a, 13b) and has a bearing surface (A). At least an end portion on one side in a circumferential direction of the body portion (13c) is raised radially inward with respect to the inner circumferential surface (11a) of the outer member (11).

摘要： An air-operated double diaphragm pump, wherein the pump (40) is disposed with a shaft (30) and a bushing (28). The shaft (30) includes a plurality of indentations which allow passage of air and the bushing (28) is adapted to receive the shaft (30) and be in sliding engagement with the shaft (30). The bushing (28) includes vents (22) formed on the bushing and a hole (24) formed at each respective terminal portion of the bushing (28) to allow passage of air. The bushing (28) also includes ribs (26) protruding radially outwards from inner surface of the bushing (28) toward the shaft (30). The indentations (34) disposed along the shaft (30) and hole (24) formed at each terminal portion of the bushing (28) are alignable to create a path for air to travel.
