[Problem] To enable high-pressure lubricating oil to be reliably supplied to a fluid chamber in a compression mechanism for supplying high-pressure lubricating oil of a stationary-side oil groove to a movable-side oil groove. [Solution] A compression mechanism (40) is configured so as to perform: a first action in which among a stationary-side oil groove (80), a movable-side oil groove (83), and a fluid chamber (S), only the stationary-side oil groove (80) and the movable-side oil groove (83) are communicated; and after the first action, a second action in which the movable-side oil groove (83) is communicated simultaneously with both the stationary-side oil groove (80) and the fluid chamber (S). |
