The pump flow increases as soon as the engine speed is raised and increases the force against orifice (7).\u003cbr\u003eAt a certain engine speed piston (6) lifts up from the seat and control pressure (Pst) is generated.\u003cbr\u003eThe (Pst) pressure moves the servo piston, which moves the swash plate to the selected travel direction (forward or reverse).\u003cbr\u003eThe higher the engine speed, the greater the HST charge pump oil flow and the bigger the force to orifice (7). As a result the control pressure increases in accordance with the engine speed and so the travel speed increases.\u003cbr\u003eThe remaining oil flows to charge pressure port (Psp) to charge the HST circuit and to PPC.","brand":"Uploader","offers":[{"title":"Default Title","offer_id":53602130886987,"sku":null,"price":58.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0978\/2519\/4315\/files\/1-11_a967633e-a795-422e-abc7-fbcb02ee8873.png?v=1760448023","url":"https:\/\/manualbull.com\/products\/komatsu-wa65-6-wa70-6-wa80-6-wa90-6-wa100m-6-loader-service-manual-workshop-guide","provider":"ManualBull","version":"1.0","type":"link"}
