    Abstract: An inline valve includes a sliding piston having a radially outer stop portion with a forward end. A radially inner sliding portion is connected to the radially outer stop portion by an arm. A housing includes an outer housing body surrounding the piston. The housing has a stop surface selectively in contact with the forward end of the radially outer stop portion of the piston to block flow for a housing inlet to a housing outlet. The radially inner sliding portion slides on a support tube. At least a portion of the radially inner sliding portion is formed of a first material having better wear resistance than a second material forming the outer stop portion of the piston. The second material has a greater resistance to high temperature and pressure than the first material. A vent valve for a compressor is also disclosed.

    Abstract: A coaxial liquid pressure regulator includes a housing having an inlet portion and an outlet portion, a substantially tubular valve member slidingly accommodated inside the housing and having a longitudinal axial passage and an upstream end with an inlet edge for the liquid, a valve body fixed inside the inlet portion and defining a seat that interacts with the inlet edge of the valve member and forms therewith a port having a variable width. The inlet portion includes an inlet fitting and a collection chamber directly downstream from the inlet fitting and the valve body includes a cantilever element transversely extending from the inner wall of the collection chamber. First and second deflection elements are arranged between the inlet fitting and the inlet edge, which facilitate flow conveyance toward the port and the longitudinal passage of the valve member.

    Abstract: A pressure regulating device for a liquid includes a main hollow body having an inlet end and an outlet end for the liquid, which are connected via a longitudinal passage, a tubular valve member, which is slidingly accommodated in the passage and has a regulating end upstream from the flow of the liquid, a seat placed inside the passage, upstream from the valve member, and having a transverse surface formed in the passage to interact with the regulating end of the valve member and define therewith a part having an adjustable width for the liquid. The seat is eccentrically supported in the passage and is formed of one piece with the main body, and is supported proximate to the inlet end for the liquid by a pair of longitudinal support wings substantially parallel to the flow direction.

    Abstract: The present invention relates to a balancing valve spool and a pressure regulating valve comprising the balancing valve spool. The balancing valve spool comprises a valve rod; a piston sleeve fixed on the valve rod; and a fixing piece sleeved between the valve rod and the piston sleeve and arranged along a direction in parallel with an axis of the valve rod. In one embodiment of the present invention, by connecting the fixing piece onto an actuator of the valve and arranging the fixing piece between the valve rod and the piston sleeve along the direction of the axis of the valve rod, an effect of guiding the valve rod is achieved and a sealing effect of isolating inlet pressure and outlet pressure is simultaneously achieved. Compared with the related arts, this design has the advantage of simple structure.
