Title:
CYLINDER BODY FIXED HYDRAULIC MOTOR
Document Type and Number:
WIPO Patent Application WO/2021/160005
Kind Code:
A1
Abstract:
A cylinder body fixed hydraulic motor, comprising a static flow distribution surface and a rotary flow distribution surface. The static flow distribution surface is provided with a cylinder hole window (101), an oil inlet window (102) and an oil outlet window (103), the rotary flow distribution surface is provided with a flow distribution window (301), and the flow distribution window (301) is a groove recessed inwards along the rotary flow distribution surface; when a plunger (105) is in an oil outlet section (201), the cylinder hole window (101) in communication with the plunger (105) is in communication with the oil outlet window (103) by means of the flow distribution window (301), and an oil liquid is discharged from a cylinder hole (104); when the plunger (105) is in an oil inlet section (202), the cylinder hole window (101) in communication with the plunger (105) is in communication with the oil inlet window (102) by means of the flow distribution window (301), and the oil liquid enters the cylinder hole (104); the flow distribution window (301), the oil inlet window (102) and the oil outlet window (103) on the flow distribution surfaces are all arranged on a cylinder hole window belt. The hydraulic motor can effectively reduce the width of a flow distribution belt, so that the structure of a flow distributor is more compact; and under the condition that the width of the flow distribution belt is not increased, the variable displacement of the hydraulic motor can also be achieved by disconnecting a part of an oil inlet channel of the oil inlet window.
