Title: CONTROL APPARATUS FOR A HYDRAULIC MOTOR
Title: APPAREIL DE COMMANDE POUR MOTEUR HYDRAULIQUE
Abstract:
A control apparatus for a hydraulic motor (3) comprises a control valve (11), a compensating valve (17) and a load pressure conduit (9). Each load pressure sensing point (23, 24) is associated with its own over-pressure valve (29, 30). Each of the two starting sections (21, 22) of the load pressure conduit (9) has a throttling point (27, 28). Behind it there is a branch conduit with the over-pressure valve (29, 30). The starting sections (21, 22) are connected to the rest (26, 8) of the load pressure conduit (9) by way of a change-over valve (25).

Title: CONTROLLER FOR HYDRAULIC MOTOR
Abstract:
PURPOSE: To vary allowable pressure in a motor pipe in accordance with a working direction by providing a branch pipe furnished with one restriction and an overpressure valve on each of introduction parts and connecting the introduction parts to a remaining part of a load pressure pipe through a selector valve. CONSTITUTION: Two introduction parts 21, 22 are provided on a load pressure pipe 9. The introduction part 21 is connected to a load pressure sensing part 24 and the introduction part 22 is connected to a load pressure sensing part 23. The introduction part 21 is connected to an overpressure valve 29 through a branch pipe, and the introduction part 22 is connected to an overpressure valve 30 through the branch pipe, and restrictions 27, 28 are respectively provided on the introduction parts 21, 22.
Consequently, as it is possible to adjust the overpressure valves 29, 30 respectively to different working values, it is possible to change working pressure in accordance with a working direction of a hydraulic motor 3.

Title: Dual load-sensing passage adjustable relief valves for hydraulic motor control
Abstract:
There is provided control apparatus for controlling fluid flow between a bidirectional motor, a pump and a container, and includes a control valve that has a slide operative between neutral and first and second operative positions. A compensating valve is provided in the supply conduit that holds the upstream pressure drop at the control valve substantially constant and is controlled by load pressure sensing circuitry. The load pressure circuitry includes two branches that are connected through a change over valve to the compensating valve. There is provided an over pressure valve and a throttle point in each branch, each branch being connected to a load pressure sensing orifice of the control valve housing and fluidly connected through the slide to one of the housing motor orifices, the one depending upon whether the slide is in its first or in its second position.
The circuitry permits the actuating pressure for operating the motor in one direction to be different from that for operating it in the other direction.
