摘要： A safety apparatus for a combustion engine includes a rotary member disposed in a rotating portion of the internal combustion engine, a spiral spring supported by the rotary member at one end and biasing the rotary member in a predetermined direction, an engaging member engaging with the other end of the spiral spring, a housing for receiving the spiral spring, and a guide member arranged over at least the outer side periphery of the overlapping portion of the spiral spring and extending along the circumferential direction of the spiral spring to prevent the spiral spring from expanding in diameter. With this construction, when breakage is caused in the spiral spring, hooking of the broken end onto the engaging member can be prevented by the guide member. Therefore, it can prevent the throttle valve from being biased toward opening direction by the broken spiral spring.

摘要： An opening end of a concave portion of a bearing holder is crimped to prevent an outer race of a ball bearing from sliding rearwardly, so that a bearing stop cover in the prior art is not needed to stop the slide-out of the outer race. Thus, the number of parts and assembling procedures for an intake air controller are reduced, thereby reducing the manufacturing const thereof. Further, since the bearing stop cover is not needed, the axial length of the bearing holder of a throttle body is shortened, thereby axially compacting the throttle body.

The fluid control valve further includes a valve member for controlling a fluid flow in the fluid passage by communicating and blocking by the fluid passage. The fluid control valve further includes a protection member being press-inserted into the housing for protecting the housing from heat of the fluid flow in the fluid passage.

摘要： A fluid control valve assembly is disclosed that includes a housing, a valve with a ring-shaped groove, and a seal ring with a clearance extending between an outer diameter and an inner diameter. The seal ring includes a pair of opposing axial side surfaces and is provided in the groove. The seal ring seals against the housing when the valve is in the closed position. The valve assembly also includes a backup ring provided in the groove adjacent one of the axial side surfaces of the seal ring to thereby obstruct fluid flow through the clearance of the seal ring when the valve is in the closed position.

摘要： An electromagnetic valve includes a valve case, a covering member, a valve member, an urging device, and an electromagnetic driving unit. The case includes a side wall; a bottom wall; an opening; a peripheral end face; a valve accommodating part eccentrically relative to a central axis of the opening; and a first port. The covering member includes a top plate part welded on the end face to cover the opening; a second port; a cylindrical part; and a valve seat on an end face of the cylindrical part. The valve member is accommodated in the accommodating part, and engaged with/disengaged from the valve seat to close/open a flow passage of fluid between the first and second ports. The case includes an auxiliary wall symmetrically to the side wall located closer to a valve axis with respect to a shorter symmetry plane. The plate part is welded on an opening-side end face of the auxiliary wall.
