Patent number: 10012282Abstract: A flow of hydraulic oil induced by sliding movement of a piston in a cylinder is controlled by a damping force generating mechanism to generate a damping force. A flow of hydraulic oil from a casing of the damping force generating mechanism toward a reservoir is regulated by a passage groove formed on the bottom of the casing so as to be directed downward in the reservoir. Thus, the hydraulic oil is efficiently supplied to a base valve from the damping force generating mechanism even when the hydraulic oil is sucked from the reservoir into a cylinder lower chamber through a passage in the base valve during the extension stroke of a piston rod. Therefore, it is possible to suppress a sharp reduction in pressure in the lower part of the reservoir and hence possible to suppress the occurrence of aeration and to obtain stable damping force characteristics.Type: GrantFiled: March 18, 2015Date of Patent: July 3, 2018Assignee: HITACHI AUTOMOTIVE SYSTEMS, LTD.Inventors: Yusei Kimura, Yohei Katayama, Naofumi Harada, Satoshi Shimazaki

Patent number: 9511383Abstract: A liquid diffuser device for irrigation systems includes a support structure defining a first longitudinal axis with an upper passageway for a liquid jet and a lower tubular body having a bottom wall, a spherical member associated therewith having an outer surface with a predetermined average radius of curvature, a liquid jet deflecting member having an upper plate and a lower stem designed to be introduced into the tubular body and defining a second longitudinal axis. The stem interacts with the outer surface of the spherical member, to allow rotation of the stem relative to the body and nutation of the second axis relative to the first axis. The bottom surface is concave to define with the spherical member a relatively broad and substantially uniform contact surface, to reduce the local specific pressure, thereby decreasing friction, wear and vibrations on the stem and the spherical member during operation.Type: GrantFiled: January 10, 2014Date of Patent: December 6, 2016Inventor: Arno Drechsel

Patent number: 9371675Abstract: A rotary damper has a damper body having a receiving portion, and a rotor rotatably disposed in the receiving portion of the damper body. A space between an inner circumferential surface of the receiving portion and an outer circumferential surface of the rotor is divided into a plurality of pressure chambers. A rotation speed of the rotor is controlled to be at a low speed by a flow resistance of fluid filled in each of the pressure chambers when the fluid flows through gaps between an inner surface of the receiving portion and an outer surface of the rotor opposed to each other in a direction of a rotation axis of the rotor. The damper body and the rotor are relatively movable in the direction of the rotation axis of the rotor.Type: GrantFiled: August 29, 2012Date of Patent: June 21, 2016Assignee: SUGATSUNE KOGYO CO., LTD.Inventors: Kazuyoshi Oshima, Ken Shinmura, Hideki Ogasawara

Publication number: 20150083536Abstract: An apparatus for retarding rotation of a nozzle includes a hollow housing, a rotary shaft within the housing, a rotatable rotor on the rotary shaft free to move axially along the shaft, and a cam assembly coupling the rotor and shaft together in the housing such that rotor rotation on the shaft causes the cam assembly to displace the rotor axially on the shaft in a first direction. A set of springs on the shaft biases the rotor in a second direction opposite the first direction on the shaft. Finally, a viscous fluid disposed between the rotor and the housing generates a drag on rotor rotation with the shaft. Relative rotation of the rotor with respect to the shaft in conjunction with a variable gap between the rotor and housing are used to slow and thus control rotary nozzle speed.Type: ApplicationFiled: August 26, 2014Publication date: March 26, 2015Inventor: Colton Andersen
