摘要： One or more boost pumps for a liquid hydrogen fuel system are disposed within the fuel tank and fully flooded. An electrical connector of each boost pump is sealed from the fuel tank and accessible from an exterior of the fuel tank while the boost pump is installed. Each boost pump can be independently replaced using a toolbox. Each boost pump is purged of fuel before being replaced by introducing a gas at a center region of the boost pump. The toolbox and new boost pump are purged prior to removal of the old boost pump. Each boost pump can be formed from modular components.

摘要： A variable coolant pump is provided. The pump comprising: a housing comprising an impeller area and a driving area, wherein the housing has a locking plate to define the impeller area; a shaft connected to a driving element arranged in the driving area; a main impeller to drive coolant in the impeller area; a shutter to cover an outflow region of the main impeller such that an amount of the coolant delivered by the pump is variable; a control pressure pump to increase hydraulic pressure to displace the shutter; a first fluid path to feed the control pressure pump with coolant from the impeller area; a collector to collect driven coolant in a region between the main impeller and the locking plate, wherein the collector is in fluid communication with the first fluid path.
