摘要:
A wax-pellet thermostat has a valve seat (1), a piston (8) secured to the valve, a guide member (6) slidably mounted on the piston, a valve (4) secured to the guide member, a diaphragm (9) secured to the guide member, and a wax (10) provided in the cylinder. A gap (14) is provided in the guide member around the piston so as to accumulate coolant entered along the piston. The gap is provided to discharge the coolant from the guide member when the wax expands to cause a part of the diaphragm to enter into the gap.

The present invention provides a hydro-actuator thermostat system for controlling a temperature of an engine. The hydro-actuated thermostat system includes a thermal responsive valve system configured to induce opening of a temperature responsive valve upon an increase of a temperature of a coolant fluid, and to induce closing of the temperature responsive valve upon a decrease of a temperature of the coolant fluid. The hydro-actuated thermostat system further includes a hydraulic actuator system controllable by a controller, wherein the hydraulic actuator is associated with a thermal responsive valve system and configured to induce opening and/or closing of the temperature responsive valve in response to an indication from the controller, the opening and/or closing of the temperature responsive valve may be performed by controlling a fluid flow to and/or from the hydraulic actuator.
摘要:
The present invention provides a radical polymerization method that enables synthesis, at a high conversion rate, of polymers having a relatively uniform molecular weight and is applicable to various monomers that are generally available, and an apparatus used for the method. The present invention relates to a method for producing a polymerization product by continuously or intermittently circulating, within a flow path of the radical polymerization apparatus, a reaction solution containing a monomer and a radical polymerization initiator. Heating of the reaction solution that has flowed into a heating-initiation unit to a predetermined temperature is performed in a condition in which the radical polymerization initiator, contained in a volume obtained when the reaction solution that has flowed into the heating-initiation unit is temporally sliced, is cleaved all at once (a condition in which the radical polymerization initiator contained in the volume is heated to the predetermined temperature simultaneously across the radial direction of a cross section of the flow path). The present invention relates to a radical polymerization reaction apparatus including a heating medium production unit 10, a heating medium-reaction solution mixing unit 20, a cooling unit 30, and a recovery unit 40 for a reaction mixture, all of which are communicatively connected by the flow path. The present invention relates to a radical polymerization reaction apparatus including a heating reaction unit 60, a cooling unit 70, and a recovery unit 80 for a reaction mixture, wherein all of which are communicatively connected by the flow path.
摘要:
A thermoregulator comprises a valve body (102) internally provided with an accommodating cavity (108) and a thermal element (204, 205) mounted in the accommodating cavity (108). The accommodating cavity (108) is in communication with the exterior through at least three ports such as a first port (104), a second port (105), and a third port (106). The thermal element is mounted in the valve body (102) through two elastic components (203, 206). A fixedly mounted annular closure ring (111) is disposed in the accommodating cavity (108). At least most of the thermal element (204, 205) is located between the third port (106) and the closure ring (111). Through such arrangement, rapid heating of transmission fluid is ensured when the temperature of the transmission fluid is low, thereby ensuring the lubrication performance of a transmission. In addition, a processing precision requirement for components and parts can be reduced and manufacturing and mounting are more convenient.

An object of the invention is to provide a hot and cold water mixing device (1) for reducing degradation in the measurement accuracy of a flowmeter (21). In the device (1) according to the invention, the flowmeter (21) is disposed in one of a hot water supply path (11) and a cold water supply path (12), having a higher flow rate. At least first and second temperature sensors (231, 232) are individually disposed in at least two of the hot and cold water supply paths (11, 12) and a mixed water path (14). A hot and cold water adjustment unit (13) adjusts a mixing volume of hot water and cold water based on measurement values of the flowmeter (21) disposed in one of the flow paths having a higher flow rate, a mixed water path flowmeter (22) and at least the first and second temperature sensors (231, 232).

摘要:
[Problem] To provide a thermo valve for which the number of components is minimized, the structure is simplified and reduced in size, the weight is reduced, and having smooth operability and improved durability. [Solution] A valve chamber (12) is provided within a housing (1) and communicating with a first flow path (21) via an aperture (23). A second flow path (13) and a third flow path (14) are provided opening into this valve chamber. Furthermore, within this valve chamber are provided a thermo element (15), which is arranged so as to be capable of advancing and retreating in the axial direction and which operates in response to the fluid temperature, thereby opening or closing the connection between the second and third flow paths, and a coil spring (18), which biases this thermo element in the direction in which the flow path is closed. A valve body (24) is provided in the aperture connecting the first flow path and the third flow path (which communicates with the valve chamber). This valve body serves as a bypass valve (22) that opens and closes the aforementioned aperture, enabling the first and third flow paths to be connected when the aperture is open, and this valve body also serves as a spring means that biases the coil spring in the direction in which the flow path is closed.
