Hydrostatic transmission assembly, with cross-port relief - YRGULANAL · 模型 127331
This valve assembly provides high pressure cross-port relief protection and a flushing circuit for hydrostatic transmissions. The hot oil flushing circuit allows a discharge of oil from the low pressure side of the loop. The charge pump replaces the hot, dirty oil with cool, filtered oil. The hot oil discharge is often passed through the cases of the pump and the motor, flushing hot, dirty oil from them as well. A unique feature of the hot oil shuttle is that the setting of the hot oil relief can be confirmed or adjusted when the transmission is in neutral. When the transmission is in neutral the charge pressure is controlled by the charge pump relief. When the hot oil shuttle opens, some or all of the charge pump flow is redirected to the hot oil relief. The charge pump relief must be set higher than the hot oil relief to produce hot oil flow. The higher the differential pressure between the 2 reliefs, the higher the hot oil flow. The amount of hot oil flow is determined by the pressure vrs flow curves of the 2 reliefs and is difficult to quantify. The standard setting of the hot oil relief is 200 psi (14 bar) at a flow of 4 gpm (16 L/min). Hydraulic motors leak. Therefore a mechanical brake is recommended to positively lock any stopped live load.
