1.-2. Flow dividing valve for hydraulic regenerative devices

Abstract

This product as shown in figs No.1.1 - 1.10 is a flow dividing valve mainly used in hydraulic regenerative devices; this flow dividing valve is comprised of a main body that divides pressure oil inflowing from a hydraulic source to hydraulic device 1 and hydraulic device 2, and a lock valve that closes the flow of pressure oil when the hydraulic source is stopped, and a safety valve; the flow dividing valve is provided with a flow dividing port 1 that communicates with hydraulic device 1, a flow dividing port 2 that communicates with hydraulic device 2, a control port 1 that communicates with a control hydraulic source, and a tank port 1 and a tank port 2 that communicate with a tank; the lock valve is provided with an inlet port that communicates with the hydraulic source and a control port 2 that communicates with the control hydraulic source; 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 No.2.1 - 2.10 is a flow dividing valve mainly used in hydraulic regenerative devices; this flow dividing valve is comprised of a main body that divides pressure oil inflowing from a hydraulic source to hydraulic device 1 and hydraulic device 2, and a lock valve that closes the flow of pressure oil when the hydraulic source is stopped, and a safety valve; the flow dividing valve is provided with a flow dividing port 1 that communicates with hydraulic device 1, a flow dividing port 2 that communicates with hydraulic device 2, a control port 1 that communicates with a control hydraulic source, and a tank port 1 and a tank port 2 that communicate with a tank; the lock valve is provided with an inlet port that communicates with the hydraulic source and a control port 2 that communicates with the control hydraulic source; the parts shown by dotted lines in figs No.2.1 - 2.7 are not part of the claimed design.
