摘要： An electromagnetic valve for controlling a passage for a flow of fluid or for a difference in the pressures between an inlet (48;56) and an outlet (56;48), comprises a body (10;16;46) on which is arranged a solenoid coil (22), a bore (26) in which is slideably mounted valve member (30) progressively displaceable in response to actuation of the solenoid coil (22) between a first position and a second position. The valve member (30) and the body (46) comprises cooperating valve surfaces (54;62) defining the passage. One valve surface (62) has in axial section a variable profile so that the area of the passage, in a radial section is a predetermined function of the intensity of the current applied to the solenoid coil (22).

摘要： A power steering mechanism includes a control valve which acts both to control the flow of pressurized fluid to and from a pair of working chambers of the mechanism and as a pressure relief valve to limit the maximum pressure which may be communicated to the working chambers. The valve includes a stack of plane annular discs which are relatively rotatable and arranged coaxially with the control shaft of the steering mechanism. The discs are resiliently biased together and define valve ports and compartments which cooperate to control the flow of pressure fluid dependent upon the relative rotational positions of the discs. Rotation of the control shaft causes rotation of one of the discs relative to the others to correlate the ports and chambers so as to supply pressure fluid to one chamber and to vent fluid from the other chamber. If the fluid pressure within the compartments of the control valve should exceed a predetermined value, the resilient bias holding the discs together is overcome and the discs separate slightly to open communication between the fluid supply ports and the vent ports.Another embodiment of the mechanism includes a linkage arranged to separate the discs and an abutment which cooperates with the linkage when the mechanism reaches either end of its range of travel. The working chambers are incapacitated when the linkage separates the discs so as to prevent damage to the mechanism from a too-high fluid pressure.

摘要： The hydraulic distributor, more particularly for power steering systems of vehicles, comprises two rotary members (1-3, 9) which are so designed as to form a substantially disc-shaped cavity (8) divided up in at least one pair of working chambers (28) by arms (13, 14) belonging to one (9) of said members (or rotor). These arms cooperate with inlet (18) and outlet (24) ports in the other member (1) (or stator) so as to form control valve means for controlling activation fluid flow supplied from a pressure generating source (26). The rotor (9) has at least one intermediate arm (33) which extends into each of the chambers of the pair of working chambers (28, 43) and which cooperates with fluid passage ports (36) in the stator in order to form additional fluid flow control valve means. The first portion (of zero slope) of the torque/activation pressure curve of the distributor is controlled by the closing edge (41a) of the intermediate arm (33a) oriented towards the arm ( 14) which is associated with the outlet port (24) and also by the closing edge (38) of the arm (14) which is associated with outlet port (24) which closing edge is oriented towards the intermediate arm (33) extending into the preceeding working chamber (28, 43a).
