A bimetal member, which deforms in correspondence with the temperature in the crank chamber, is arranged in the valve chamber. A valve body, which is supported by the bimetal member, is arranged in the valve chamber. The peripheral wall has a first oil discharge passage and allows communication between the crank chamber and the valve chamber, and a second oil discharge passage through which the valve chamber and a suction chamber communicate with each other. When the temperature in the crank chamber exceeds a predetermined value and deforms the bimetal member to move the valve body, communication between the first and second oil discharge passage is permitted through the valve chamber.

This swash plate comprises a resin film layer formed on the front surface and the rear surface, and said resin film layer serves as the sliding surface which slides on a shoe. The inner periphery of the resin film layer is a tilted surface which a lubricant can easily cross over. In other words, angle θ1 is 10° or less and angle θ2 of the rising part is set to 20° or less, and when the lubricant is supplied from the inner periphery side of the swash plate, said lubricant easily crosses over said inner periphery which is a tilted surface, and is quickly supplied to the surface (the sliding surface) outside of said inner periphery. Because the lubricant is quickly supplied to the front surface and the rear surface (the sliding surface) of the swash plate, seizure of the swash plate can be prevented.

Laser hardening can be used to precisely harden selected areas of the bearing surfaces of the compressor components. By hardening those selected areas, wear resistance can be improved and sliding wear can be reduced. This can result in thrust plates having different material structures configured to contact one another, such as one having a primarily pearlitic microstructure with the opposing thrust plate having a primarily martensitic microstructure. This can reduce adhesive wear by providing dissimilarity on the wearing surfaces.

An actuator for a vehicle seat can be configured to prevent overstress of a shape memory alloy (SMA) wire. The actuator can include a first body member and a second body member pivotably connected to each other. The actuator can include an overstress post and an overstress contact plate operatively connected to the overstress post. Thus, movement of the overstress post causes movement of the overstress contact plate. The actuator can include an overstress contact pin. The actuator can include an SMA wire operatively connected to one of the body members and to the overstress post. When activated, the SMA wire can shrink, causing one of the body members to pivot relative to the other body member and causing the overstress contact plate to move toward the overstress contact pin. If the overstress contact plate contacts the overstress contact pin, the SMA wire can be deactivated.

An actuator device includes an actuator member, a drive subject, a first drive device and a second drive device. The actuator member is configured to be deformed in response to application of energy to the actuator member from an outside. The drive subject is coupled to the actuator member. The first drive device is configured to apply the energy to the actuator member and thereby displace the drive subject in a deforming direction of the actuator member. The second drive device is configured to displace the drive subject in a different direction that is different from the deforming direction of the actuator member.

Method for the production of a piston for an internal combustion engine

Номер: US20160229007A1
Автор: Gerhard Berr, Rainer Scharp, Reiner Mueller, Sascha-Oliver Boczek
Принадлежит: MAHLE International GmbH

A method for the production of a piston made of steel, for an internal combustion engine, in which the upper piston part is produced using the forging method, and the lower piston part is produced using the forging or casting method, and they are subsequently welded to one another. To simplify the production method and make it cheaper, the upper piston part is forged using the method of hot forming and of cold calibration, to finish it to such an extent that further processing of the combustion bowl and of the upper cooling channel regions can be eliminated.

Автор: Nobuya TAKAHARA
Принадлежит: Individual

An internal combustion engine includes a cylinder of which the interior is divided into two in the longitudinal direction. The lower chamber serves as a mechanical driving portion in which the piston is reciprocated. The upper chamber serves as a power portion in which combustion gas is drawn in, compressed, burned and exhausted. A cylindrical portion with a lid which moves into the power portion is continuously provided on top of the piston. A gap is defined between the cylindrical portion and the inner peripheral surface of the power portion of the cylinder. The inner peripheral surface of the power portion is defined by a heat shield tube fitted in the cylinder. A heat insulating tube is provided on the outer periphery of the heat shield tube.
