    • [0033] An apparatus and method relating to a variable compression connecting rod system (10, 110) located in an internal combustion engine including a connecting rod (28, 128) having a piston-pin-receiving aperture defining a first longitudinal axis in a first end portion and a crankpin-receiving aperture defining a second longitudinal axis in a second end portion (36), a hydraulically actuated eccentric rotor (52) rotatable about one of the first and second longitudinal axis in response to fluid pressure acting on expandable chambers (76a, 76b, 78a, 78b, 176a, 176b, 178a, 178b) defined between the rotor (52, 152) and the connecting rod (28, 128). A hydraulic actuation system (51, 151) including a fluid pressure actuated activation valve (58, 158), at least one check valve (62, 64), and a plurality of fluid passages (66, 66a, 66b, 66c, 66d, 166) in fluid communication with the expandable chambers (76a, 76b, 78a, 78b, 176a, 176b, 178a, 178b).
    • 一种与可变压缩连杆系统(10,110)相关的装置和方法,所述可变压缩连杆系统(10,110)位于包括连接杆(28,128)的内燃机中,所述连杆具有活塞销接收孔,该活塞销接收孔限定第一纵向轴线 第一端部和曲柄销接收孔,其在第二端部部分(36)中限定第二纵向轴线;液压驱动的偏心转子(52),其响应于作用在可膨胀室上的流体压力可旋转地围绕第一和第二纵向轴线中的一个 (52,152)和连接杆(28,128)之间限定的(76a,76b,78a,78b,176a,176b,178a,178b)。 包括流体压力致动活化阀(58,158),至少一个止回阀(62,64)和多个流体通道(66,66a,66b,66c,66d)的液压致动系统(51,151) 166a,176b,178a,178b)与可扩张腔(76a,76b,78a,78b,176a,176b,178a,178b)流体连通。
