摘要： A back pressure regulating valve (10) includes a valve body (14) having a fluid inlet (16), a fluid outlet (18), a central bore (20), a bonnet (22) housing a load spring (24) operatively coupled to a diaphragmn (26), and a chamber (30) in flow communication with the fluid inlet. A valve cartridge (12) includes a housing (34) sized to fit within the central bore and including a first portion (36), a second portion (38), a valve guide (40), and a flow passage (42). A valve seat (44) is disposed in the housing, and a valve plug (44) is shiftable between an open position permitting flow and a closed position preventing flow. The valve plug engages the valve guide, and a spring (52) biases the valve plug toward the open position. A retainer (54) is disposed adjacent the first portion of the housing and engages a portion of the valve plug to retain the valve plug in the housing.

摘要： The invention relates to a hydraulic rock breaking device, a protection valve and a method of operating a hydraulic rock breaking device. The rock breaking device comprises a percussion device (4) to which pressure fluid is fed along an inlet channel (13). The inlet channel is provided with a protection valve (23) arranged to monitor the volume flow of pressure fluid flowing through it. If the flow is larger than what has been preset, the protection valve closes, at least partly, the connection through it, protecting thus the percussion device against too high an input power. The protection valve comprises a throttle (38) which generates a pressure difference the magnitude of which is dependent on the fed volume flow. Information on the pressure difference is utilized in controlling the protection valve.

摘要： A pressure relief value (20), including: a housing that includes an upper portion (11) and a lower portion (12); wherein the lower portion (12) of the housing includes an inlet (4), an outlet (13), a diaphragm stopper (14) and a fluid stopper (15); a spring (7), positioned within a first chamber (16) that is surrounded by the upper portion (11) of the housing; wherein a low end of the spring is adapted to contact an upper part of a diaphragm and apply a downward pressure on the diaphragm; a diaphragm adapted to axially move within the housing; wherein the diaphragm and the lower portion of the housing (12) define a fluid chamber (8); wherein while a pressure level of fluid that enters the fluid chamber (8) via the inlet (4) is below a predefined threshold the upper part of the diaphragm contacts the diaphragm stopper (14) and a lower edge of the diaphragm contacts the fluid stopper (15) such as to prevent fluid from flowing through the outlet (13); wherein when a pressure level of the fluid exceed the predefined threshold the diaphragm immediately moves upwards and fluid flows from the inlet (4), via a space formed between the diaphragm and the fluid stopper (15) and through the outlet (13); and wherein an area of the lower edge of the diaphragm is substantially smaller that an area of a portion of the diaphragm that is subjected to upward pressure imposed by fluid located within the fluid chamber (8).

摘要： A gas release device that includes a reservoir of pressurised gas and a passageway from said reservoir to an outlet. There is an elastic gas permeable membrane in the passageway that allows gas release only via the membrane. A gas impermeable member is provided in the passageway that includes an interface positioned to contact said gas permeable membrane. Displacement of the gas permeable membrane is responsive to the pressure of the gas in the reservoir such that there is a greater interfacial contact between the gas impermeable member and the gas permeable membrane at a higher gas pressure than at lower pressure to thereby vary the exposed cross sectional area of the permeable membrane available to the flow in an inverse relationship to pressure.

摘要： The invention relates to a valve device (6) which is equipped with a soft start valve (21) in order to provide a soft start function. Said soft start valve (21) comprises main valve means (25) which are positioned to selectively block or release the connection between a primary channel (4) subjected to a primary pressure, and a secondary channel (1). Also, the soft start valve is positioned so that the secondary channel (1) is subjected, at least initially, to lower soft start pressure than the primary pressure which is generated in a soft start channel (2). A control slide (33) of the main valve means (25) is positioned so that it controls the connection between the secondary channel (1) and the soft start channel (2) or the primary channel (4) and comprises an actuation surface (57) which is subjected to soft start pressure for changing the control slide (33).
