Document Type and Number:
WIPO Patent Application WO/2022/219835
Kind Code:
A1
Abstract:
This machine tool comprises a first brake mechanism (334), a second brake mechanism (335), a first flow path (221), a second flow path (231) and third flow path (261) that branch from the first flow path (221) and supply fluid pressure to the first brake mechanism (334) and the second brake mechanism (335), respectively, a first fluid pressure maintaining mechanism (240), and a second fluid pressure maintaining mechanism (270). The first fluid pressure maintaining mechanism (240) includes a first accumulator (246) and a first check valve (241) provided farther upstream than the first accumulator (246) in terms of the flow of fluid from the first flow path (221) toward the first brake mechanism (334). The second fluid pressure maintaining mechanism (270) includes a second accumulator (276) and a second check valve (271) provided farther upstream than the second accumulator (276) in terms of the flow of fluid from the first flow path (221) toward the second brake mechanism (335).
