摘要： 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.

摘要： 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.

摘要： 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.
摘要翻译：悬挂装置配备有包括活塞部分，悬架弹簧，上部座椅和弹簧的阻尼器。弹簧布置在活塞部分和上座之间，并且是用于从阻尼器接收负载的弹性构件。弹簧具有不发生滞后的负载特性，因此动态弹簧常数可以很小。因此，在高频范围和无限小幅度范围内的振动传递减少。弹簧具有用作盘形弹簧部分的主体。因此，与阻尼器的轴线垂直的方向的弹簧常数大，因此与轴线垂直的方向的刚度提高。结果，提高乘坐质量，获得稳定的处理。

摘要： 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.
