トルク増幅装置。[Claims for Utility Model Registration] 1. A housing having an inlet port and an outlet port, an internally toothed member provided within the housing, and an external member that is located within the internally toothed member and meshes with the internal toothed member and rotates and revolves around its axis. an amplification section consisting of a tooth member, a switching valve that controls fluid flow between each port and the amplification section, an input shaft that operates the switching valve, and an output shaft that is operated by the power of the amplification section. In the hydraulic torque amplification device, the housing is provided with an auxiliary fluid port for supplying fluid to auxiliary equipment, and the switching valve is in a neutral position to allow fluid from the inlet port to flow to the auxiliary fluid port without passing through the amplification section. and is configured such that at the maximum displacement position, the fluid from the inlet port flows only to the amplifying section, and at a position intermediate therebetween, the fluid from the inlet port flows to both the amplifying section and the auxiliary fluid port. A hydraulic torque amplification device featuring: 2. A housing with an inlet port and an outlet port, an internally toothed member formed in a part of this housing, and an externally toothed member that meshes with the internally toothed member and rotates and revolves within the internally toothed member. an amplifying section consisting of; a switching valve for controlling fluid flow between each port and the amplifying section; and an input shaft for operating the switching valve;
In a hydraulic torque amplification device having an output shaft operated by power of the amplification section, the housing is provided with an auxiliary fluid port for supplying fluid to auxiliary equipment and a bypass valve disposed between the three ports, The switching valve allows fluid from the inlet port to pass through the auxiliary fluid port without passing through the amplification section when in the neutral position, and the bypass valve cooperates with the switching valve to direct fluid from the inlet port to the auxiliary fluid port when the switching valve is in a position other than the neutral position. 1. A hydraulic torque amplification device, characterized in that the fluid is configured to flow through both an amplification section and an auxiliary fluid port.
