Abstract: A fuel tank ventilation valve includes a float valve, a float control mechanism, and a barrier member. The float valve includes a float and a float chamber. The float chamber is provided by a case. The float control mechanism controls the area of a fuel opening so that a fuel outflow speed from the float chamber is slower than a fuel inflow speed into the float chamber. The barrier member is located between an opening for a ventilation passage and the float. The barrier member suppresses fuel intrusion. The fuel tank ventilation valve is capable of preventing an outflow of a liquid component.

Abstract: The invention relates to petroleum engineering, and more particularly to the design of a check valve that can be used in conjunction with downhole sucker-rod pumps or electric centrifugal pumps primarily intended for pumping fluids with a high solid particle content. A ball check valve comprises: a hollow cylindrical housing having an internal annular protrusion; a valve pair mounted inside said housing and being in the form of an annular seat and a ball locking member; and a means for limiting the movement of the closure member, which is in the form of a cage with through holes for fluid flow. Between the seat and the cage there is mounted an annular elastic member, the inner diameter of which is not greater than the diameter of the ball locking member. The annular elastic element performs a dual function: when closing the valve provides additional pressing of the ball locking element to the seat due to the arising elastic forces; and provides additional sealing.

Abstract: A system and method of collecting and disposing of fluid during a medical procedure. Fluid is drawn from a fluid source into a first reservoir in communication with a vacuum source. The fluid passes through an open fluid transfer valve into a second reservoir in communication with the vacuum source. While the fluid continues to be drawn into the first reservoir, the fluid transfer valve is closed after a predetermined volume of the fluid passes into the second reservoir. The fluid collected in the second reservoir is measured and evacuated from the second reservoir. The fluid transfer valve is opened and the steps are repeated until the medical procedure is completed while the first reservoir remains in uninterrupted communication with the vacuum source during the medical procedure such that fluid is capable of continuing to be drawn into the first reservoir without interruption.

An armature chamber is filled with hydraulic medium and fluidically connected to hydraulic lines of the hydraulic system. An armature is mounted in the armature chamber such that its stroke is adjustable. The armature includes a shut-off body and divides the armature chamber into an opening-side chamber facing the flow opening and into an inner chamber facing away from the flow opening. During a stroke of the armature, an oil exchange occurs, and a displacement volume of the hydraulic medium overflows from the opening-side chamber into the inner chamber. A hydraulic line leading to the opening-side chamber or to the inner chamber of the armature chamber includes a dirt collecting element that is designed as a permanent magnet and that retains contaminations in the hydraulic medium that flows through the hydraulic line during an oil exchange.
