摘要： The accuracy of controlling steam by a pressure reducing valve is enhanced. A steam supply passage 1 incorporates a pressure reducing valve 3 and the passage 1 further incorporates a steam ejector 4 downstream of the pressure reducing valve 3. A suction portion 4a of the steam ejector 4 is connected to a re-evaporation tank 2 for re-evaporating steam condensate D1 via a suction passage 9. Passage steam S' of the pressure reducing valve 3 is used as a driving steam for the steam ejector 4. In operation, re-evaporated steam FS within the re-evaporation tank 2 is suctioned by the steam ejector 4 to be mixed with the passage steam S'. The suction passage 9 incorporates a check valve 10 for preventing reverse flow of steam to the re-evaporation tank 2, The steam supply system described above is configured such that a valve opening ratio of the pressure reducing valve 3 is adjusted in accordance with the temperature or the pressure of the steam on the downstream side of the steam ejector 4 in the steam supply passage 1 and the check valve 10 has an inherent flow characteristics that an increase ratio of a flow rate associated with increase of its valve opening ratio is equivalent between a small opening ratio range with small valve opening ratios and a large opening ratio range with large valve opening ratios or an inherent flow characteristics that the increase ratio is smaller in the small opening ratio range than in the large opening ratio range.

摘要： A vent system for an axle of a heavy-duty vehicle includes a check valve and an exhaust tube that is connected to the check valve. The check valve includes a first end that is mounted on the axle, a second end, and a body that is disposed between the first and second ends and is in selective fluid communication with the axle interior. The exhaust tube includes a first end that is mounted on the second end of the check valve, and a second end that is open to atmosphere and is in fluid communication with the check valve body. Using any one of a number of types of configurations for the valve body, the vent system selectively exhausts air from the axle interior to atmosphere to relieve buildups of pressure in the axle, while protecting the integrity of the check valve and preventing contaminants from entering the axle.

摘要： A mud saver valve is constructed so that the valve seats self align preventing the loss of fluid when the valve is in the closed position. One or both seats can skew their longitudinal axes to get the alignment.

摘要： Disclosed is a check valve comprising a valve housing (40) which is inserted into a receiving device (34) and within which a piston-shaped valve member (60) is guided so as to be movable in a longitudinal direction, said valve member (60) cooperating with a valve seat (48) that is embodied on the valve housing (40). The valve member (60) which is inserted into the valve housing (40) from the valve seat (48) end is impinged upon by a biased closing spring (70) in the closing direction and by the pressure prevailing in an inlet (44a) in the opening direction. The valve housing (40) is configured in a pot-shaped manner as a single piece and is provided with a bottom (42) and a jacket area that delimits a recess (41). The open end of the recess (41) of the valve housing (40) protrudes from the receiving device (34) while the valve seat (48) is disposed on the bottom (42) of the valve housing (40) and faces away from the recess (41). A shaft (62) of the valve member (60) extends through a bore (44b) located in the bottom (42) and into the recess (41) inside which the closing spring (70) is arranged.

摘要： The invention relates to a backflow preventer (1) comprising a valve member (6) in the interior (5) of the insertable housing (2) thereof. Said valve member (6) sealingly rests against a valve seat (7) in the closed position thereof while being movable from the closed position thereof into the open position thereof counter to a restoring force. The interior (5) of the housing is provided with an interior section (A) which has an interior cross section that is larger than the outer circumference of the valve member in the movement zone of the valve member (6). The aim of the invention is to prevent undesired noise from developing as a result of the valve member (6) vibrating on the inner circumference of the housing also when the quantity of penetrating medium is low. Said aim is achieved by providing at least the movement zone of the backflow preventer (1), which is located near the valve seat (7), with an elastic valve member guide (9) that is effective between the valve member (6) and the interior housing wall surrounding the interior section (A) so as to guide the valve member (6) free from play.

摘要： A check valve (10) for a fuel pump (12) of a vehicle includes a valve housing (26) adapted to be disposed in an outlet member (20) of the fuel pump (12) and a valve seat (36) formed on the valve housing (26). The check valve (10) also includes a valve member (38) disposed in the valve housing (26) and having a closed position to engage the valve seat (36) to prevent fuel from flowing through the outlet member (20) and an open position to allow fuel to flow through the outlet member (20). The valve housing (26) has a vortex abating geometry (48) located near the valve seat (36) to add turbulence to fluid flow past the valve seat (36) when the valve member (38) is in the open position.
