Problems solved by technology

In addition, if the motor uses a small working displacement, the braking torque is low and the braking efficiency is poor
In fact, the purpose of this system is to avoid damage to the pump and its drive motor, but it does not solve the problem of insufficient braking for small displacements

Embodiment Construction

[0052] figure 1 The motor 1 in comprises a housing having four parts 1A, 1B, 1C and 1D, inside which is mounted a rotating cylinder block 10 capable of rotatably driving a main shaft 12 which is held by a bearing 14 relative to the housing part 1A support. Inside the housing part 1C there is provided an internal distributor 16 with distribution ducts, with which the cylinders 18 of the cylinder block can communicate successively through their cylinder ducts 19 during the rotation of the cylinder block, wherein the distributor is in rotation fixed relative to the housing. The piston 17 of the cylinder block 10 is supported by the bellows cam 4 formed at the inner periphery of the housing portion 1B. Although the motor shown is of the fixed housing type with a rotating spindle, the invention is also applicable to rotating housing motors.

[0053] The motor consists of at least two main conduits C1 and C2 (see figure 2 ), which serve as the input and discharge of the motor, ...

Abstract

A motor having two series of distribution ducts each having two groups of ducts. The displacement selector (30) is able to occupy a large displacement position (i) in which the first groups of distribution ducts (I1 and II2) of the first series are connected to a main duct (L1) while the second groups (I2 and II2) are connected to the other main duct (L2), and a small displacement configuration (ii) in which the first group of distribution ducts (I1) of the first series is connected to a main duct, the second group of distribution ducts (I2) of the first series is connected to the other main duct and a bypass connection exists between the first and the second group of distribution ducts (II1 and II2) of the second series. The device has a restriction (42 and 48) in order, in the small displacement configuration, to restrict this bypass connection.

Description

technical field [0001] The invention relates to a device for managing the displacement of a hydraulic motor having at least two effective working displacements and capable of being connected to two main conduits respectively for input and discharge, the motor comprising two series of distribution conduits, Each series has first and second sets of distribution ducts; the management device includes a displacement selector capable of occupying at least a high displacement position and a low displacement setting in which , the first set of distribution lines of the first and second series are connected to one main line, and the second set of distribution lines of the first and second series are connected to another main line; in this small displacement setup, the first series The first set of distribution pipes of the first series are connected to one main pipe, while the second set of distribution pipes of the first series are connected to another main pipe, and the first set of ...
