Document Type and Number:
WIPO Patent Application WO/2017/169642
Kind Code:
A1
Abstract:
Provided is a variable-displacement swash-plate-type compressor with which restarting after operation of the clutch can be performed smoothly. Each cylinder bore comprises first and second cylinder bores 21a and 23a. Each piston 9 has a first head section 9a partitioning the interior of the first cylinder bore 21a into a first compression chamber 53a and a second head section 9b partitioning the interior of the second cylinder bore 23a into a second compression chamber 53b. A link mechanism 7 is arranged such that the top dead center position of the second head section 9b moves by a greater amount than the top dead center position of the first head section 9a in conjunction with a change in the inclination angle. The compressor also is equipped with a first reverse flow part 73, 74 that is provided only on one surface 5a side of the swash plate 5, and that leaks coolant in the first compression chamber 53a into a first intake chamber 27a, and/or a second reverse flow part 71, 72 that is provided only on the other surface 5b side of the swash plate 5, and that leaks coolant in a second discharge chamber 29b into the second compression chamber 53b, and increases the pressure P2 inside the second compression chamber 53b so as to be greater than the pressure Ps inside a swash plate chamber 33.
