摘要:
An internal combustion engine, including a combustion chamber with a first aperture; a compression chamber with a second aperture; and a crossover valve comprising an internal chamber, first and second valve seats, a valve head, and first and second valve faces on the valve head, wherein the first aperture allows fluid communication between the combustion chamber and the internal chamber, the second aperture allows fluid communication between the compression chamber and the internal chamber, the first valve face couples to the first valve seat to occlude the first aperture, and the second valve face couples to the second valve seat to occlude the second aperture.
摘要:
The present invention relates to a flow control valve that controls the flow rate of heated water that is supplied from a boiler, in a pipe line through which the heated water flows. It is an object of the invention to provide a flow control valve that can normally/reversely turn and control the flow rate using two low price one-way motors and stop power for one motor when the other motor is rotated by applying a simple clutch structure to a gear assembly connected with two one-way motors. A flow control valve according to an embodiment of the invention includes: a motor assembly including a first motor that has a power transmission shaft and rotates in one direction and a second motor that has a power transmission shaft and rotates in the opposite direction of the first motor; a gear assembly including a first planetary gear that transmits power to the first motor, a second planetary gear that transmits power to the second motor, and a sun gear that is disposed between the first planetary gear and the second planetary gear and engaged with the first and second planetary gears, and having a clutch structure between the first planetary gear and the first motor, and the second planetary gear and the second motor to transmit or stop power; and a valve actuator including a shaft that reciprocates up/down by rotation of the sun gear and a valve unit that is fitted on the lower portion of the shaft and opens/closes the valve.

A valve (100a) that has at least one internal port (130a) on a valve core (102a) and at least one an internal slot (154a) in a valve body (108a). The valve core (102a) is biased into a position wherein the port of the valve core is aligned with a sealing surface (126a) of the valve body thereby prohibiting fluid flow through the valve. The valve core (102a) is slidable such that the port of the valve core becomes aligned with the internal slot (154a) of the valve body thereby allowing fluid flow through the valve. Another valve includes a self-aligning valve seat carrier (200c) which is pivotably engaged with a valve core member. The self-aligning valve seat carrier engages a sealing surface in a valve body to prohibit fluid flow through the valve, but the valve core is slidable such that the self-aligning valve seat carrier disengages from the sealing surface in order to allow fluid flow through the valve.

La soufflette (B) comprend un corps (51) sensiblement tubulaire apte à coopérer avec des moyens d'immobilisation (10) à l'intérieur d'un élément femelle (A) de raccord rapide pour maintenir ce corps en position dans un alésage central (la) de l'élément femelle et une buse (54) globalement tubulaire apte à déplacer, par coulissement à l'intérieur du corps, un clapet (3) de l'élément femelle, le coulissement de la buse dans le corps étant commandé par un levier (55). La soufflette (B) peut être montée ou démontée rapidement par rapport à l'élément femelle (A) du raccord rapide. Elle permet donc de transformer un élément femelle de raccord rapide en outil de nettoyage.
