STRUCTURE AND FUNCTION CLSS 3.5 DIVIDING FUNCTION (1:9) (Only Super-Flow specification for SK815-5) Function 1 When each section is operated individually Attachment: 60L/min High-Flow attachment: 100L/min 2 When standard attachment and high flow attachment are operated at the same time 1:9=attachment: High-Flow 1 3 2 A Attachment section High-flow section RKS00711 Operation 1 When each section is operated individually Attachment spool (1) and High-Flow spool (3) stroke fully and individually, therefore they keep demand flow rate in- dividually. Attachment: 60L/min High-Flow: 100L/min 2 When attachment and High-Flow are operated at the same time.
High-Flow attachment PPC pressure passes through passage A , is sent to retainer (2) and makes retainer (2) stroke to the left. When this happens, attachment spool (1) can stroke by half. As a result, flow rate of attachment and High-Flow are divided as below expression. Attachment: High-Flow= 1:9 Therefore flow rate of high flow is kept. 10-46 SK818-5 SK820-5 turbo
