A molded coil includes a bobbin, a coil, and an exterior member. The coil is wound around the bobbin, and generates a magnetic force in reaction to power supply. The exterior member covers the coil and the bobbin therewith. Two seams, a first seam and a second seam are provided between the bobbin and the exterior member. A first seal member is disposed on an upstream side of the first seam and between a cover member and the exterior member. A second seal member is disposed on an upstream side of the second scam and between a flange portion of a stator core main body and the exterior member.

Provided is a temperature-driven valve assembly which can be manufactured in a cost-effective and simple manner as well as a gas pressure spring including the valve assembly which enables more reliable and safer operation of the gas pressure spring.

Sealing device including a first seal and a second seal each having an annular support formed in the manner of a sleeve and delimited by a first and second face which are situated opposite each other and a first and second annular sealing elements; wherein the first and second annular sealing elements are independent and separate from each other and are fixed integral with a first portion and a second portion of the annular support which are different from each other and are made of a first and second elastomer mix, the second elastomer mix being different from the first mix and having a greater hardness and higher elastic modulus; at least one annular sealing element being provided radially on the inside with at least one annular lip which extends radially and axially in cantilever fashion from a first end of the annular support.

A damper comprises a pressure tube extending longitudinally between a first pressure tube end and a second pressure tube end, a piston arranged in sliding engagement inside the pressure tube, a piston rod coupled to the piston, a hydraulic rebound stop positioned in a first working chamber and including a sealing ring circumferentially extending around the piston rod and within the pressure tube. The sealing ring at least partially defining a high-pressure region within the pressure tube during a rebound stroke the damper further comprising a pressure relief valve in fluid communication with the high-pressure region. The pressure relief valve being operable to allow pressurized fluid from the high-pressure region to pass therethrough once a predefined pressure threshold has been reached.

A shock absorber including a pressure tube, a piston assembly slidably disposed within the pressure tube, and a fluid transfer tube that extends about the pressure tube, and a reserve tube that extends about the fluid transfer tube is provided. The piston assembly divides an inner volume of the pressure tube into first and second working chambers. An intermediate chamber between the pressure tube and the fluid transfer tube is arranged in fluid communication with the first working chamber. A reservoir chamber between the fluid transfer tube is arranged in fluid communication with the intermediate chamber. An insert is disposed within the intermediate chamber, reducing the volume of the intermediate chamber and defining a fluid transfer channel between the first working chamber and the reservoir chamber.

A universal tube adaptor for a shock absorber includes a connector body, and first and second connectors. The connector body has intersecting first and second connecting holes respectively and rotatably receiving the first and second connectors rotatably therein. The first connector has a first guiding hole and an overflow hole perpendicular to, in fluid communication with, and cooperating with the first guiding hole to define an oil-filled space in fluid communication with the second connecting hole. The second connector has a second guiding hole in fluid communication with the second connecting hole and the overflow hole, so that the second guiding hole, the oil-filled space and the first guiding hole cooperate with one another to define an oil passage permitting damping oil to flow therein.

A solar tracker system includes a torque tube, a solar panel assembly attached to the torque tube, a housing defining a chamber and a fluid passageway extending from the chamber, and an active lock connected to a seal configured to prevent a flow path of fluid while in a sealed state and allow the flow path of fluid in an unsealed state. The system further includes a controller in communication with the torque tube and the active lock. The controller is programmed to receive a command to place the solar panel assembly in a stowed position, instruct the torque tube to rotate the panel assembly to a stowed angle corresponding to the stowed position, monitor a current angle of the panel assembly, compare the current angle to the stowed angle, and instruct the seal to transition to the sealed state when the current angle is equal to the stowed angle.

A manufacturing method for a cylinder device which includes a cylinder, a piston, a piston rod, a seal member, and an installing member, the method includes: a welding step for fixing the installing member to the cylinder through electrical resistance welding; a demagnetizing step for demagnetizing at least an opening portion of the cylinder; and an assembling step for assembling the piston, the piston rod, and the seal member in the cylinder through the opening portion.

A damper including inner and outer tubes and a control valve. A piston is slidably disposed within the inner tube to define first and second working chambers. An intermediate member assembly is disposed annularly about the inner tube. An intermediate channel is positioned radially between the intermediate member assembly and the inner tube and a reservoir channel is positioned radially between the intermediate member assembly and the outer tube. A first unidirectional blocking valve forms a first partition between first and second intermediate channel portions of the intermediate channel. A second unidirectional blocking valve forms a second partition between the second intermediate channel portion and a third intermediate channel portion. An external control valve has a control valve inlet that is arranged in fluid communication with the second intermediate channel portion.

Providing a sealing member which can successfully scrape off foreign substances and prevent failure caused by incorporation of foreign substances. A dust seal serving as a sealing member includes a dust seal body and a lip member. The dust seal body has a predetermined elasticity and is retained in an opening of an outer tube into which an inner tube reciprocated in a projected state is inserted. The lip member is harder than the dust seal body and is attached to a distal end of the dust seal body. The lip member has a distal end which is brought into sliding contact with an outer peripheral surface of the inner tube.
