Description
(54) ГИДРАВЛИЧЕСКИЙ ПРИВОД РАБОЧЕГО ОБОРУДОВАНИЯ ЗЕМЛЕРОЙНОЙ МАШИНЫ(54) HYDRAULIC DRIVE OF WORKING EQUIPMENT OF DIGGING MACHINE
И в золотнике 12 со сливом. Рабочий орган 1 при этом находитс в плавающем положении .And in the spool 12 with a drain. The operating element 1 is in this case in a floating position.
Таким образом обеспечено плавающее положение исполнительного органа, что расшир ет функциональные возможности устройства .Thus, the floating position of the executive body is ensured, which expands the functionality of the device.
