1.-3. Pressure booster as part of a hydraulic regenerative device

Abstract

This product as shown in figs. 1.1 - 1.7 is a pressure booster mainly used in hydraulic regenerative devices; this pressure booster is integrated with a main body that boosts the pressure of the inflowing pressure oil and an accumulator that accumulates the pressurized pressure oil; the main body has an inlet port that communicates with a hydraulic source, a tank port for communicating with a tank, and a discharge port for discharging the pressure oil from the storage part of the accumulator to the outside; the parts shown by dotted lines in figs No.1.1 - 1.7 are not part of the claimed design; this product as shown in figs. 2.1 - 2.7 is a pressure booster mainly used in hydraulic regenerative devices; this pressure booster is integrated with a main body that boosts the pressure of the inflowing pressure oil and a cover; the main body has an inlet port that communicates with a hydraulic source, a tank port for communicating with a tank, and a discharge port for discharging the pressure oil; the parts shown by dotted lines in figs. 2.1 - 2.7 are not part of the claimed design; this product as shown in figs. 3.1 - 3.7 is a pressure booster mainly used in hydraulic regenerative devices; a main body of the pressure booster has a tank port for communicating with a tank, and a discharge port for discharging a pressure oil.
