Booster for fixed amount of oil emission

摘要

Topic In order to prevent the breakdown and damage of the equipment which is concatenated to set pressure the booster for constant flow emission which can make raise the pressure is offered.SolutionsThis invention discloses the booster for constant flow emission. This invention, the hydraulic pump, the hydraulic motor and the offering/accompanying oil supply path, 1st control means and includes 2nd control means. The hydraulic pump the pumping doing the oil pressure inflow delivers oil pressure via the emission channel. The hydraulic motor Drive by the oil pressure inflow, in order to make the oil pressure raise the pressure which is delivered by the hydraulic pump, Drive the hydraulic pump. The offering/accompanying oil supply path makes oil pressure the hydraulic pump and the hydraulic motor supply. 1st control means make the supply channel open, as for 2nd control means when the oil pressure which is delivered from the emission channel is higher than configuration oil pressure, in order for 1st control means to make the supply channel close, the fact that 1st control means are operated is feature. According to this invention, when pressure of the discharged oil path is higher than set pressure, 1st control means and with 2nd control means as for the offering/accompanying oil supply path there is an effect which can prevent the fact that than set pressure it is high raised the pressure by being cut off. Because of this, as for this invention there is an effect which can prevent the breakdown and damage of the equipment which is concatenated to the booster. In addition, this invention not only raising the pressure, continuing capacity, because it is possible, to deliver evenly, continuing the hydraulic motor and the hydraulic cylinder, there is an effect which can apply to the existing equipment which it operates. Choice figure It is not
