A valve, comprising: a housing, a holder, a first valve body, a bearing, and a second valve body. The housing comprises a first housing part, a second housing part, and a neck connecting the first housing part and the second housing part, a first valve body cavity is formed in the first housing part. The holder is provided in the second housing part, the holder and the second housing part together form a second valve body cavity and a pump cavity, the holder and the neck together form a bearing accommodating part for enabling the first valve body cavity to be in fluid communication with the pump cavity. At the bearing accommodating part defined by the holder and the neck, a limiter is provided, the limiter extends towards the bearing, the bearing has a receiving part, and the limiter cooperates with the receiving part to restrict movement of the bearing.

A valve device includes a body that defines a passage through which a fluid flows, a shaft that is movably supported with respect to the body and defines an axis, a valve element that is fixed to the shaft to open and close the passage; and a cylindrical bearing bush that movably supports the shaft with respect to the body, in which the bearing bush includes a mixed region in which a metal core material and expanded graphite are mixed with each other, and a first expanded graphite region made of only the expanded graphite such that the metal core material is not exposed in an inner circumferential side region in contact with an outer circumferential surface of the shaft.

A sintered bearing includes a bearing main body which has a substantially cylindrical shape and is made of a sintered material, a through-hole being formed in a center of the bearing main body; a sealing member in a disk shape, the sealing member being configured to be disposed such that one surface side of the sealing member is in contact with the bearing main body, and an opening being formed in a center of the sealing member; and a locking member in a block shape, the locking member being configured to be in contact with at least another surface side of the sealing member and holding the sealing member between the locking member and the bearing main body.

A bearing system includes a first bearing, the first bearing being annular in shape and defining a ring aperture, the first bearing including a first surface and a second surface, a second bearing being substantially the same in construction to the first bearing, a first surface of the second bearing contacting a second surface of the first bearing, wherein each of the bearings is constructed of nylon MDS.

Bearings and valves are provided that include diamond engagement surfaces that are engaged with opposing, metal engagement surfaces that include diamond solvent-catalyst. Also provided are methods of making and using the bearings and valves.

A valve member is mounted on a shaft to pivot within a fluid passage. A control selectively moves a piston in a linear direction to control a position of the valve member in the fluid passage. The piston causes a roller pin to move as the piston moves linearly. The roller pin is mounted in crank collars of a crank shaft such that movement of the roller pin causes the crank collars to rotate crank shaft rotating position, and the valve shaft. The roller pin is mounted within the crank collars by bearings. The bearings each have an outer race associated with a crank collar, an inner race associated with the roller pin, and bearing members separate the inner and outer race. There is a spring bias resisting movement of the inner races relative to said roller pin. An anti-ice system is also disclosed.

A control system (1) for operating a mechanical function is disclosed. The system (1) includes a lever (11), a housing (13) and at least one control cable (3). The lever (11) is pivotable and includes at least one seat (9) for receiving a first coupling element (17) of the at least one control cable (3). The control system (1) further includes at least one adapter element (23), and the housing (13) further includes at least one first recess (25). The at least one seat (9) of the lever and the at least one first recess (25) of the housing (13) include first and second open spaces (33, 35) that are aligned with each other in an assembly direction (37). This allows for a simultaneous coupling of the first coupling element (17) to the at least one seat (9) and the adapter element (23) to the at least one first recess (25) of the housing (13), along said assembly direction (37).

Provided is a sintered bearing for an EGR valve, including raw material powder including 9% by weight to 12% by weight of aluminum, 0.1% by weight to 0.6% by weight of phosphorus, 3% by weight to 10% by weight of graphite, and the balance including copper as a main component, and inevitable impurities. The sintered bearing has a structure of a sintered aluminum-copper alloy. The sintered bearing further includes free graphite distributed in pores formed so as to be dispersed.
