Filed: 1989-12-19
Granted: 1997-05-17
Abstract: A 3-way valve for a fluid distribution pipe-line comprises a main section (2) intended to be joined to this distribution pipe-line and a branch section (5) intended to be connected to an inlet/outlet pipe, which communicates with the main section via an opening (9) formed in the wall of this main section and entirely contained in the extension of the inner volume of the branch section (5). A movable closing element (10) adapted to close this opening or otherwise is situated between the branch section (5) and this opening; it comprises a spherical plug (11) through which a cylindrical bore (14) passes and which is adapted to turn through at least 90 DEG  about an axis (Z-Z) transverse with respect to the axis (Y-Y) of the branch section, between a passage configuration and a closed configuration in which the spherical plug, owing to its spherical outer wall, is flush with the inner volume of the main section.

Abstract: PCT No. PCT/SE88/00399 Sec. 371 Date Jan. 11, 1990 Sec. 102(e) Date Jan. 11, 1990 PCT Filed Aug. 8, 1988 PCT Pub. No. WO89/01375 PCT Pub. Date Feb. 23, 1989.A cutting insert, especially for turning tools, comprising an insert body having a transverse front cutting edge portion and a rear portion for mounting on and clamping to an insert holder, a cutting surface which connects with said cutting edge being provided with a central chip-forming recess. The novelty of the invention resides in that the chip-forming recess has a concave bottom surface which connects with the transverse cutting edge and with the rest of the cutting surface at a distance from said cutting edge, and that said recess is laterally restricted by inclined, convex sides having a curvature and shape relative to the concave bottom surface such that the bottom surface width at first decreases, as seen in the direction away from the cutting edge and backwards, and then increases again.

Abstract: A gear motor includes a group of reducing gears equipped with a clutch among them, which are  between  a  motor  and  an  output member for driving. A clutch operating mechanism is  connected  to the clutch for joining/unjoining operations. The clutch  operating mechanism arranges  a  permanent  magnet  and  induction  ring  to transfer rotating power by  magnetic  induction,  and  includes  a clutch operating bar whose position is changed freely between  the clutch joining position and the  unjoining  position.  The  clutch operating bar lies usually on the unjoining position.  The  clutch operating bar is moved to the joining position because one side of the permanent magnet is rotated by magnetic  induction  while  the other side is connected to the motor.

Title: Power steering device for vehicle
Inventor: CHOE BYONG-YUN
IPC: B62D5/06
Filed: 1993-06-02
Granted: 1995-10-24
Abstract: The device using the subsidiary power supply device of the hydraulic actuator, has a hydraulic cylinder(50) for generating the subsidiary steering power from the hydraulic pump, hydraulic control valve(54) for proportionally controlling the hydraulic power fed from the cylinder(50) according to the relative movement between the valve body(58) and the casing(56) and a power reacting device(68) for variably suppressing the relative movement between the body(58) and casing(56) according to the vehicle speed. The power reacting device(68) comprises polygonal section(70) formed at the valve body, reacting chamber(72) between the casing(56) and the housing(44), vehicle speed pump(74) for supplying the pressure fluid, and a pair of sliders(80) having an axial groove(82) having a form engaged with the corner of the polygonal section.
