Abstract
The lubrication loop 5 includes a first lubrication flow path L4, a release flow path L6, a low pressure fluid discharge valve 13, a return flow path L7, and a discharge flow path L8. In the low pressure fluid discharge valve 13, an accumulator piston 22 is biased to the other end side of a piston housing chamber 21 by a spring 26 when a pressure of the fluid applied to a piston position control chamber 27 is less than a predetermined pressure so that a supply port 24 and a discharge port 25 communicate with each other via a spool groove 32.
