Abstract: An expansion valve (1) for a vapour compression system, the valve (1) comprising a first valve part (5) having an outlet orifice (7) and a piston (8) movable inside the outlet orifice (7) in response to a differential pressure across the expansion valve (1), controlling a fluid flow through the valve (1). The piston (8) comprises a stop element (9) at an outlet end (8b) of the piston (8) and mechanical forcing means (10) to force the piston (8) towards a position in which the stop element (9) is brought into abutment with a valve seat (12) of the first valve part (5). A differential pressure below a predefined threshold value causes the stop element (9) of the piston (8) to abut the valve seat (12) of the first valve part (5), preventing fluid flow through the first valve part (5), via the forward fluid passage.

Abstract: A ventilation arrangement for the head space of the fuel tank of a vehicle consists of a valve assembly received in a housing (30), which assembly is arranged to produce a maximum pressure, which is not to be exceeded, a minimum pressure below which the pressure must not fall, and a random pressure, for example, for the tank filling process, within the head space. For this purpose a valve which is biased by a spring (25) in the direction towards an atmospheric connector (6) and is characterised by a sealing plate (17), and a valve biased by a spring (19) in the direction towards a connector (5) intended for connection to the head space, and a valve characterised by a sealing head (24) are provided, the latter of which is simultaneously connected to an electromagnetic drive in order to produce the random pressure. As a result of the constructional combination of all three valve functions in the housing (30), the mutually coaxial guidance of the sealing head (24) and of the sealing plate (17), a valve assembly is provided which takes up a small construction volume and is suitable in particular for use under the spatially limited installation conditions of a hybrid vehicle.

Abstract: A decoupled check-relief valve for use in a hydraulic fluid circuit is provided that has a cylindrical guide housing which travels during the check function of the valve. The cylindrical guide housing has a clearance parameter, allowing for the selection of an optimal check response time. A dampening disk is provided inside the cylindrical guide housing, traveling within the guide during the relief function of the valve. The dampening disk has a separate clearance parameter, allowing for the selection of an optimal dampening capacity and fluid circuit stability. As such, the check and relief clearance parameters are independent of each other to allow both the check and relief functions of the valve to be optimized.

Abstract: A combination or hybrid pressure relief and topping valve for use with inflatable devices such as life rafts and escape slides. The valve including a valve body with a fluid passage therein that includes an internal shoulder. The valve further includes a first poppet with a seal seated therein where the first poppet is biased against the shoulder by a first spring.

Abstract: A hydraulic system including at least one hydraulic cylinder is provided with an anti-cavitation and overload relief valve having a housing, a first chamber within the housing in fluid communication with one end of the cylinder, and a second chamber within the housing in fluid communication with a fluid reservoir. A fluid passageway within the valve housing connects the first and second chambers. A movable valve assembly is positioned within the fluid passageway for operating in a plurality of modes for providing anti-cavitation and overload relief. The valve includes a stationary portion positioned within the fluid passageway between the first and second chambers having a valve seat. The movable valve assembly includes a poppet mechanism for sealingly engaging a valve seat of the movable valve element when the movable valve assembly is operating in first and third modes. A tang on the head of the poppet engages a reduced diameter portion of the stationary valve element in order to maintain fluid communication between the first and second chambers during the second mode of operation. An axial extension of a poppet spring seat limits the travel of the movable valve during the third mode of operation and limits the stress on a poppet spring.

Abstract: A pressure vacuum vent has a body with means to vent an underground tank having vapors therein when the pressure within the tank exceeds a predetermined pressure and to allow ambient air pressure to enter the tank when the tank has a vacuum exceeding a predetermined vacuum. The body has a housing, which is open at its upper end, mounted thereon and extending upwardly therefrom with a cap mounted on top of the housing and spaced from the top of the housing to form passage means therebetween to allow vapor from the tank to flow upwardly therethrough. A cylindrical shaped shroud, which is preferably a single continuous member, is disposed in surrounding relation to the cap and the upper end of the housing to prevent any driven moisture from entering the passage means formed between the housing and the cap while still allowing vapor to flow only upwardly from the passage means through the shroud.
