Abstract
Pressure regulator device comprising a body (1), a minimum of a pressure reducer and a damper mounted in control and damping cavities, respectively, in the body (1), and a control member (4) pivoting on an upper face (10) of the body (1). The device is noteworthy in that the control and damping cavities have open ends in a peripheral face (12) of the body (1) and the control member (4) has parts (47) that are opposite the peripheral face (12) in order to face the open ends of the respective control and damping cavities, from which control (21) and damping pushrods, respectively, project. The present invention has an application us the hydraulic remote controls of civil engineering machines.
Claims12
A pressure regulator device, in particular of the hydraulic remote-control type, comprising:
- a body provided with two end faces, lower and upper, respectively, and a peripheral face extending between the two end faces, and comprising at least one so-called control cavity emerging on at least one of said faces and at least one so-called damping cavity emerging on at least one of said faces,
- a minimum of a pressure reducer mounted in the body and comprising a control push-piece housed in back and forth motion in the at least one control cavity, said pressure reducer being intended to enable the control of at least one receiver outside the regulator device,
- a control member pivoting relative to the body, at least one hinge mounted on the upper face of said body, in order to control the back and forth movement of the at least one control push-piece, and
- at least one damper mounted in the body and comprising two damping push-pieces arranged on either side of said hinge and housed in back and forth motion in said at least one damping cavity, said damper being intended to damp the tilting of the control member in both directions, said control member pushing on one hand one of said damping push-pieces when it tilts in one direction, and on the other hand the other of said damping push-pieces when it tilts in the other direction,
- wherein the at least one control cavity has one end emerging in the peripheral face of said body, wherein the at least one damping cavity has two ends emerging in the peripheral face of said body on either side of said hinge of the control member, and wherein the control member has portions opposite the peripheral face to face the emerging ends of the control and damping cavities, respectively, from which the control and damping push-pieces emerge, respectively.
