Patent number: 8950739Abstract: The first corner portion elastically deforms in application of load such that the angle of the first corner portion changes depending on the pressing force from the first member. In this case, the first corner portion can move toward the outside of the inner periphery portion of the main body portion while the angle changes. The second corner portion has the same function as that of the first corner portion, and it can move toward the outside of the outer periphery portion of the main body portion while the angle changes depending on the pressing force from the second member in the elastic deformation of the second corner portion. As a result, the spring can prevent generation of hysteresis in load characteristics without increasing the number of parts, and enables height adjustment of the spring.Type: GrantFiled: May 8, 2009Date of Patent: February 10, 2015Assignee: NHK Spring Co., Ltd.Inventors: Norihiro Tajima, Jun Tominaga, Hidemasa Ito

Publication number: 20130069293Abstract: A suspension device is equipped with a damper including a piston portion, a suspension spring, an upper seat, and a spring. The spring is arranged between the piston portion and the upper seat and is an elastic member for receiving a load from the damper. The spring has load characteristics in which hysteresis does not occur, whereby a dynamic spring constant can be small. Therefore, transmission of vibrations in a high-frequency range and an infinitesimal amplitude range is decreased. The spring has a main body that functions as a disc spring portion. Therefore, the spring constant in a direction perpendicular to an axis line of the damper is large, whereby stiffness in the direction perpendicular to the axis line is increased. As a result, ride quality is improved, and stable handling is obtained.Type: ApplicationFiled: May 19, 2011Publication date: March 21, 2013Applicant: NHK SPRING CO., LTD.Inventors: Hidemasa Ito, Jun Tominaga, Norihiro Tajima

Patent number: 8312853Abstract: A valve spring device is provided with a first coil spring and a second coil spring combined in series with each other. The inside diameter (coil inside diameter) of the second coil spring is greater than the outside diameter (coil outside diameter) of the first coil spring. A part of the first coil spring including an end portion along an axis is inserted into the second coil spring, thereby forming a combined spring. The end portion of the first coil spring and an end portion of the second coil spring are connected to each other by a connecting member. The first and second coil springs are compressed along the axis as they are located in series between a cylinder head and a retainer. A shaft of a valve is passed within the coil springs.Type: GrantFiled: February 12, 2010Date of Patent: November 20, 2012Assignee: NHK Spring Co., Ltd.Inventors: Kazuo Iwata, Noritoshi Takamura, Jun Tominaga, Norihiro Tajima

Patent number: 8025039Abstract: A port is formed in a cylinder head of an engine. The port is opened and closed by a valve. A valve spring device is provided with a first spring and a second spring. The second spring is contained in a housing and held by a stopper in a manner such that it is compressed along an axis or subjected to a preload. The preload of the second spring is larger than an installation load of the first spring. An axial load acts on the springs. The valve spring device has load-deflection characteristics such that only the first spring deforms axially when the axial load is not larger than a predetermined value and that both the first and second springs deform axially when the axial is load exceeds the predetermined value.Type: GrantFiled: August 12, 2009Date of Patent: September 27, 2011Assignee: NHK Spring Co., Ltd.Inventors: Kazuo Iwata, Noritoshi Takamura, Jun Tominaga, Norihiro Tajima, Takeshi Yabushita
