| description | To provide a construction machine on which a hydraulic circuit comprising a variable displacement pump and a selector valve is mounted, in which a pump assembly is downsized, and in which a variable displacement pump is easily maintained.SOLUTION: A construction machine comprises a pump assembly and a selector valve. The pump assembly comprises a variable displacement pump with a variable discharge amount. The discharge amount from the variable displacement pump varies by switching an operation state of the selector valve. The selector valve is provided as a separate body from the pump assembly at a position separated from the pump assembly.SELECTED DRAWING: Figure 2
【課題】容量可変ポンプ及び切替え弁を備える油圧回路が搭載されるとともに、ポンプアセンブリの小型化が実現され、容量可変ポンプのメンテナンスを行い易い建設機械を提供すること。【解決手段】建設機械は、ポンプアセンブリ及び切替え弁を備える。ポンプアセンブリは、吐出量が変化可能な容量可変ポンプを備える。切替え弁の作動状態が切替わることにより、容量可変ポンプからの吐出量が変化する。切替え弁は、ポンプアセンブリとは離れた位置に、ポンプアセンブリとは別体で設けられる。【選択図】図２ |
