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 valve timing adjustment device is configured to adjust an opening/closing timing of a valve by rotation of a cam shaft driven by a motor through a speed reduction mechanism. The speed reduction mechanism includes a rolling bearing and a thrust receiver. The rolling bearing includes a raceway groove to guide a rolling element at a surface of an inner ring and a surface of an outer ring. The raceway groove includes a deep groove provided at one side with respect to a center of the rolling element, and a shallow groove provided at the other side with respect to the center of the rolling element. The thrust receiver includes a first draining portion to discharge lubricating oil to outside of the rolling bearing from the shallow groove of the outer ring.

A valve and a bearing surface for a valve and a manufacturing method of the same including a valve body with a main channel extending between a fluid inlet and a fluid outlet, and a closing member provided in the main channel. The valve further includes a shaft connected to the closing member for moving the closing member between an open and a closed position. Moreover, the valve includes at least one bearing surface between the valve body and the closing member or the valve body and the shaft, the bearing surface further including a plurality of cavities filled with solid lubricant. An advantage of the claimed valve is that the lubricant is maintained longer on the bearing surfaces and thus lubrication periods and valve lifetime are increased.

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 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 fluid flow control device includes a valve body forming a channel defining a fluid flow path extending from an inlet to an outlet, a shaft having a first portion and a second portion, a flow control member coupled to the first portion of the shaft, and a bearing comprising an elongated body having a first end, a second end, an inner surface defining an interior volume, and an outer surface. The bearing is dimensioned to accommodate the shaft in the interior volume and includes at least one opening extending between the inner surface and the outer surface and at least one elongated channel formed on the outer surface. The elongated channel extends a length between the first end and the second end of the elongated body.

An electromagnetic actuating device. The device includes an electromagnetic coil including a central recess extending in an axial direction, a cylindrical pole tube inserted into the central recess and provided with a magnetic separation point, an armature situated displaceably in the pole tube, the armature being movable by an actuation of the electromagnetic coil, the armature being mounted in the pole tube in a sleeve-shaped bearing foil inserted into the pole tube, the bearing foil including an inner side facing toward the armature and used as a sliding surface and an outer side facing toward the cylindrical pole tube. It is provided that the bearing foil is coated at least on the inner side using a first layer made of perfluoroalkoxy polymer. A manufacturing method for such an electromagnetic actuating device is also described.

A shaft-bearing bush assembly for a valve arrangement for an air-conditioning system is disclosed. The shaft-bearing bush assembly includes a shaft drive-connectable to a valve of the valve arrangement and a bearing bush, in which the shaft is rotatably received relative to the bearing bush between a first rotary position and a second rotary position about an axis of rotation extending along the axial direction. A bush projection is non-rotatably arranged on the bearing bush relative to the bearing bush and a shaft projection is non-rotatably arranged on the shaft relative to the shaft. The bush projection and the shaft projection are matched to one another such that the bush projection provides a rotary stop for the shaft projection for limiting the rotary movement of the shaft between the first rotary position and the second rotary position.

The valve includes a valve body that inwardly defines a passage for circulation of a fluid, a drive shaft, and a bearing to guide the rotation of the drive shaft. The bearing comprises a chamber surrounding a segment of the drive shaft and a plurality of balls filling the chamber. The balls are free inside the chamber, and the chamber is completely filled with balls. The balls are in contact with the drive shaft along all or part of the segment.

A bearing bushing (1) and to a method for manufacturing a bearing bushing are provided. The bearing bushing includes a wire article (2) formed from knitted wire mesh or knitted wire fabric (6) and compressed into a dimensionally stable compressed product (3). The bearing bushing can be provided for supporting a throttle valve used in high-temperature applications. The wire article (2) is formed from a stainless steel. Existing voids (10) of the compressed product (3) are filled with solder (4).
