Electrical contact comprising a contact element, which has a connection portion, which serves for the electrical conducting connection to an electrical conductor, but a contact holding portion connected integrally to the connection portion, for contacting a counter contact, and a support element, which encloses the contact holding portion at least at a portion of its length along a longitudinal axis and formed in cross-section as a hollow rectangle delimited by four walls, has along the longitudinal axis a front end and a rear end facing the connection ports. Further, the support element has along the longitudinal axis (4) a front end (16) and a rear end (17), with the rear end (17) facing the connection portion (5), has a first projection (18) close to the front end (16), which first projection (18) has a first insertion portion (19) which distance from the longitudinal axis (4) increases in a direction from the front end (16) towards the rear end (17) and has side walls (22) and ends with an end edge (20), has a second projection (23) close to the rear end (17), which second projection (23) has a second insertion portion (24), which distance to the longitudinal axis (4) increases in a direction towards the rear end (17) in an inclined manner away from the first projection (18) relative to the longitudinal axis (4), wherein the first projection (18) as well as the second projection (23) are formed by non-cutting working from one of the walls (12, 13, 14, 15), so that they project away from the longitudinal axis (4) from that wall (14).

A hollow seal for use in sealing between relatively movable first and second panels, such as between a fixed window panel and a slidable window panel of a rear window of a pick-up truck or the like. The hollow seal has an internal geometry that supports an outside layer or portion of the seal under pressurization to prevent leakage and seal blowout. The outside portion is shaped to provide a pair of laterally spaced-apart sealing lips that have a pressure-activated sealing geometry for tight sealing against the panels when under pressurization.

The valve 10 includes a valve main body 11 having an opening 11A and forming a space which creates a part of a gas flow path, a first valve member 12, provided in the valve main body, for opening / closing the opening 11A, and a drive mechanism 40 for moving the first valve member 12 between a close position where the opening 11A is closed and an open position where the opening 11A is opened, wherein the drive mechanism 40 has a rod 14 to be reciprocated, an end of the rod 14 extends into the valve main body 11 through a through hole 11B formed in the valve main body 11 to be connected to the first valve member 12, the first valve member 12 is moved between the close position and the open position as the rod 14 is driven reciprocated, and the valve further comprising a sealing mechanism 15, which communicates into the valve main body 11 via the through hole 11B, for isolating the drive mechanism 40 side air-tightly from the valve main body, and a second valve member 17, provided on the rod 14 to move together with the rod 14 as it is reciprocated, which closes the through hole 11B when the first valve member 12 is situated at the open or close position so as to isolate the sealing mechanism 15 with respect to the valve main body 11.

A fuel cell includes a plurality of fuel cell units. Each fuel cell unit includes an electrode assembly having electrodes and an electrolyte, a pair of separators, and gas sealing members. At least two of the fuel cell units include at least two electrode assemblies and at least three separators. In each of the separators, reaction gas communication ports are provided. In one of the separators of one of the stacked fuel cell units that is located at the end in a direction of stacking, through paths are formed. In one of the separators of one of the stacked fuel cell units that is located at the other end in the direction of stacking, reaction gas communication paths are formed. Both the through paths and the reaction gas communication paths are formed in all separators that are located between two fuel cell units that are located at the ends.

An air bag type grouting hole packer comprises grouting pipes and a plurality of annular cloth bags, the annular cloth bags are arranged at intervals and comprises inner walls and outer walls, the outer walls and the inner walls are sealed to form closed spaces, the closed spaces serve as grouting sealing cavities of the annular cloth bags, sections extending along the outer walls and the inner walls of two ends in the length direction of each annular cloth bag form grouting holes communicated with the corresponding grouting sealing cavity, and the grouting pipes sequentially penetrate the annular cloth bags through the grouting holes. By the aid of the annular cloth bags with new structures, the annular cloth bags comprise inner walls and the outer walls, the inner walls enclose through holes for placing gas drainage pipes, the outer walls are arranged outside the inner wall in sleeved manner, so that the grouting sealing cavities formed by the outer walls and the inner walls are uniformly distributed outside the gas drainage pipes, the acting force of the grouting sealing cavities to the gas drainage pipes is uniform after grouting, and damage to the gas drainage pipes is avoided.

An injector comprises a cylindrical body portion, a holding ring capable of centering an axial center of the injector, and a small-diameter cylindrical portion. There are provided an assembly forming step of forming a fuel rail assembly by inserting the injectors into respective cup portions via spring members for reaction force absorption, a press inserting step of pressing and inserting respective tip-side portions of the injectors by pressing pressure-receiving portions such that the respective spring members are compressed up to a middle compressive state thereof with a pressing movable apparatus which is capable of pressing the pressure-receiving portions of a fuel rail via respective pressing springs, and a fastening step of fastening plural boss portions concurrently to a cylinder head in a state in which a pressing force of the press inserting step is maintained.

One embodiment provides a control valve filter device, including: a belt-like frame body curved into a ring shape so that its ends face each other, the frame body having an opening; a filter member provided in the opening of the frame body; an engagement claw extended from one of each of both corresponding lateral portions of the faced ends of the frame body; and a concave portion provided at the other of each of the both corresponding lateral portions of the faced ends of the frame body, so as to be engaged by the engagement claw, each concave portion being formed laterally of the opening of the frame body.
