摘要： A gear pump includes a pair of gears accommodated in a gear chamber. When the inside pressure of a trap region which is changed with the rotation of the gears becomes substantially equal to the inside pressure of an inlet chamber, the communication state is switched from a state in which communication between the trap region and the first and second relief channels is blocked to a state in which the trap region communicates with the second relief channel. With the inside pressure of the trap region being substantially equal to the inside pressure of the inlet chamber, the trap region is opened to the inlet chamber.

摘要： A torque transmission chain and torque transmission device of which the strength of links is increased by devising lock points that regulate the maximum relative rotation angle between the links are provided. Lock points that contact with pins and interpieces to regulate the maximum relative rotation angles are provided at four portions, that is, a front surface of a link front pillar portion, a rear surface of a link rear pillar portion and a front surface and rear surface of a link intermediate pillar portion. Each of allowable maximum relative rotation angles regulated by the lock points of a link outline portion is set so as to be smaller than each of allowable maximum relative rotation angles regulated by the lock points of the link intermediate pillar portion.

摘要： An object of the invention is to provide a power transmission chain capable of effectively reducing noises and a power transmission assembly using the same. In the power transmission chain including plural links each possessing through-holes and plural pins inserted through the through-holes for interconnecting the plural links, all the plural pins substantially have the same longitudinal length while the plural pins include plural types of pins which have mutually different rigidities against force acting in the pin longitudinal direction. Furthermore, a locus of contact position between the pin and a strip is defined by an involute of a circle. The pins and strips are combined to form two or more types of pairs which provide the involutes of base circles having different radii.

摘要： A chain (1) includes plural links (2) and plural pairs of first and second pins (3 and 4) to couple the links each other. The first pin (3) comes into rolling and sliding contact with the second pin (4) at the contact portion (D). The first pin (3) includes a pair of end faces (17) opposing each other in the chain width direction (W), and a contact region (24) that comes into contact with the corresponding sheave surfaces of the pulley is formed in each end face (17). The contact region (24) includes the center point of contact (M). The first pin (3) includes a first type pin (3a) and a second type pin (3b). When the linear region of the chain (1) is viewed in the chain width direction (W), the relative position of the contact portion (D) and the center point of contact (M) is different between the first type pin (3a) and the second type pin (3b).

摘要： A power transmission chain (1) has links (11), pins (14), and interpieces (15). The links (14) each have a front and a back insertion parts (12, 13) through which the pins are inserted. The pins (14) and the interpieces (15) connect links (11) that are arranged side by side in the lateral direction of the chain such that the front insertion part (12) of one of the links (11) and the rear insertion part (13) of the other link (11) correspond to each other, and the connection is made such that that the links (11) are bendable in the longitudinal direction. The locus of a contact position of a pin (14) and an interpiece (15) is an involute of a circle. Two or more kinds of sets of a pin (14) and an interpiece (15) having different radii of base circles of involutes are formed, and these sets of a pin (14) and an interpiece (15) are randomly arranged.

摘要： The end faces of a first pin contain bulging curved faces having an egg-like shape, when viewed along a chain width direction. Each bulging curved face includes a first end portion, a second end portion and a maximum width portion with respect to a chain advancing direction. With respect to perpendicular directions, the distance between the center of the maximum width portion and the first end portion is relatively large, whereas the distance between the center of the maximum width portion and the second end portion is relatively short. It is possible to enlarge the surface area of the bulging curved face.
