Title:
PISTON TYPE SWASH PLATE COMPRESSOR
Document Type and Number:
Japanese Patent JP2017150438
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve the durability of a sliding bearing while actualizing good lubrication between the sliding bearing and a rotor.SOLUTION: A rotor 17A has an internal passage 30. In the rotation phase of a top dead center corresponding part 19a of a swash plate 19 to a piston 22, an opening 43a of the internal passage 30 at the side of a second supporting part 42 is at a phase position on the opposite side to the top dead center corresponding part 19a. As a result, when radial load works on the second supporting part 42 in association with the movement of the rotor 17A to the side of the top dead center corresponding part 19a of the swash plate 19 in the radial direction of a rotary shaft 17, the opening edge of the opening 43a of the internal passage 30 hardly slide on the second supporting part 42. Then, the lubricating oil is supplied from the inside of a swash plate chamber 16 directly between the second supporting part 42 and the rotary shaft 17 and in addition the lubricating oil is supplied via the internal passage 30 between the second supporting part 42 and the rotary shaft 17, thus increasing the amount of the lubricating oil to be supplied between the second supporting part 42 and the rotary shaft 17.SELECTED DRAWING: Figure 1
