摘要: A split-flow-type flowmeter in which an end portion of a flow splitter tube 1 is inserted into a main-flow pipe 10 having a diameter D. A flow splitter tube 1 includes a U-shaped split-flow passage 1a. A detection element is disposed at a bottom portion (not shown) of the U-shaped split-flow passage 1a. The split-flow passage 1a assumes a flow path structure symmetrical with respect to a plane passing through the detection element. A flow inlet 2a and a flow outlet 2b of the split-flow passage 1a face in mutually opposite directions along the flow direction of the main-flow pipe 10 and open symmetrically at the same position on the flow cross section of the main-flow pipe 10. In order to divert into the split-flow passage 1a a portion of relatively high flow rate of flow from the main-flow pipe 10, the center of opening of the flow inlet 2a/flow outlet 2b is positioned between the center of the flow cross section of the main-flow pipe 10 and an average-flow-velocity position at which flow in the main-flow pipe 10 is of an average flow velocity, as observed on the flow cross section of the main-flow pipe 10.

摘要: A flow measurement device is disclosed, in which an accumulation of pollution substance onto a detection element is prevented, and which can measure a reverse flow similarly to a normal flow. On both ends of an outer wall 23 outer peripheral portion of a divided flow pipe 20 having a &OHgr;-shape pipe passage, there are oppositely formed an inlet port 25 and an outlet port 26, which open in faces orthogonal to a flow direction of a main flow M that is a detection object. Within the divided flow pipe 20, by a curved partition 27, plural branch flow passages 28a, 28b mutually branching and joining in the divided flow pipe 20 are formed. Inside both end portions of the outer wall 23, undulation portions 32, 33 are formed so as to clog an inlet and an outlet of the outer peripheral side branch flow passage 28a and, by this, throttles are formed respectively in a flow passage between the inlet port 25 and the inlet of the branch flow passage 28a and a flow passage between the outlet port 26 and the outlet of the branch flow passage 28a. In a bottom portion of the outer wall 23 of the divided flow pipe 20, a detection element 31 is attached so as to be exposed to a flow in the outer peripheral side branch flow passage 28a and, against its detection face, a down flow DW further divided from a divided flow D obliquely impinges.

摘要: A flow rate and flow velocity measurement device. A part of a flow 10 in a main flow pipe 1, which is a detection object, is introduced into a passage of a divided flow pipe 2 and becomes a flow 11. The divided flow pipe 2 has a curved portion 2c or rather an inverted arc portion in which the flow is abruptly changed in direction or rather inverted by protuberances 2a, 2b formed preferably in symmetry in upstream and downstream sides of the curved portion 2c. Outside the main flow pipe 1, there is disposed on the bottom portion of the curved portion 2c of the divided flow pipe 2 a detection element 5 fixed to a support body 4 while protruding preferably 0.05-0.3 mm from flow passage faces 2e, 2f in the vicinity thereof. An opposed face 2d opposite to the detection element 5 protrudes toward the detection face so as to throttle the passage and to accelerate a flow speed at the element. Thus, in the curved portion 2c from the flow 11, a down flow 12 is constantly formed obliquely impinging against the detection face of the detection element 5, improving flow measurement accuracy within a wide flow speed range.

摘要: A glow plug including a pressure sensor (830) and a heater (150). The glow plug includes a position-defining member which defines the positional relationship between the pressure sensor (830) and the heater (150) and has a coefficient of thermal expansion greater than that of the heater. The pressure sensor (830) is fixed at a predetermined sensor reference position relative to the position-defining member. The heater (150) is held by a heater-holding member (820) in such manner that an attachment position A of the heater-holding member to the heater can be displaced, with a change in external pressure, relative to a predetermined heater reference position defined by the position-defining member. A displacement transmission member (840) is arranged between the heater (150) and the pressure sensor (830) so as to transmit displacement of the heater (150) to the pressure sensor (830). The coefficient of thermal expansion of the displacement transmission member (840) is rendered greater than that of the position-defining member.

摘要: A glow plug in which a convex portion (70) is formed in an outer peripheral surface (10b) of a heater (10) in a part facing an inner peripheral surface (137b) of a leading end part (137) of a housing (110) and interposed in a leading end side annular gap K1, so as to maintain a gap with the inner peripheral surface (137b).

摘要: A seal member (60) has a dual-tube structure consisting of an outer tubular seal member (160a) and an inner tubular seal member (160b); the outer tubular seal member (160a) is welded, at its rear end portion, to the inner circumferential surface of a forward-end housing (131), thereby forming a housing-side joint W2; the inner tubular seal member (160b) is welded, at its forward end portion, to a forward end portion of the outer tubular seal member (160a), thereby forming an inter-tubular-seal-member joint W3; and the inner tubular seal member (160b) is welded, at its portion located rearward of the joint W3, to the outer circumferential surface of the heater (10), thereby forming a heater-side joint W1. An action of pressing the heater forward is effected on the basis of an axial dimension L1 between the joints W2 and W1 shorter than an axial dimension between the joints W2 and W3 and is, therefore, mitigated.
