在进行单作用高压小流量的液压系统设计时,一般习惯采用典型的增压器增压系统,代替高压油泵作为动力源。这种典型的增压器增压系统,由于考虑到系统泄漏的不可避免,保证系统正常工作,从而在系统中设置了由单向阀1和补油箱2组成高压端的补油装置(图1)。但由于补油箱的设置,使其紧 In the design of a single-acting high-pressure low-flow hydraulic system, it is customary to adopt a typical turbocharger pressurization system instead of a high-pressure pump as a power source. This typical turbocharger supercharging system, due to the unavoidable system leakage, to ensure the normal operation of the system, which set up in the system by the check valve 1 and fill the fuel tank composed of 2 high-pressure side of the charging device (Figure 1) . But because of the fill tank set to make it tight
