A tire pressure gauge includes a tubular housing, a pressure measuring head connected to one end of the tubular housing, a pressure responsive piston provided inside the tubular housing and biased by a spring towards a pressure inlet hole of the pressure measuring head, and a plunger actuated by the piston and having a portion that extends out of the other end of the tubular housing. An adjustable extension member, which is disposed between the piston and the plunger, is connected to the plunger to adjust the length of the outwardly extending portion of the plunger or to correct the position of the graduations provided on the plunger relative to a pointing end of the tubular housing where a detected pressure is read. Preferably, the adjustable extension member is a screw member which is threadedly connected to the plunger. Adjustment or correction can be made before or after assembly by turning the screw member relative to the plunger.

A flow control valve assembly is adapted for use with a water conveying device which is provided with a supply channel, a valve chamber, first and second outlet passages communicated fluidly with the valve chamber, and a mounting hole. The flow control valve assembly is mounted to the water conveying device at the mounting hole with the use of a tubular mount, and includes a piston shaft movable between a first valve position, where water from the supply channel flows through the second outlet passage, and a second valve position, where water from the supply channel flows through the first outlet passage. The flow control valve assembly further includes a temperature sensor for detecting the temperature of water in the valve chamber, and an indicator unit associated operably with the temperature sensor so as to indicate the water temperature in the valve chamber thereon.

A shoe with an electronic step counter including a shoe body, a fluid bladder, a pressure sensor, a temperature compensator, a transmitting circuit, and a receiving circuit. The shoe body has a vamp and an outsole having a receiving space for receiving the fluid bladder. The pressure sensor contacts the fluid in the fluid bladder to detect the pressure thereof and generating a pressure voltage signal. The temperature compensator communicates with the fluid in the fluid bladder, detects the temperature thereof, and generating a temperature voltage signal. The transmitting circuit is disposed in the receiving space of the outsole and connected to the pressure sensor and the temperature compensator. The transmitting circuit receives the pressure voltage signals and the temperature voltage signals, convert them into a value which is emitted in a radio signal. The receiving circuit is disposed separate from the transmitting circuit and may receive the radio signal from therefrom. The receiving circuit demodulates and decodes the received radio signal and display the thus obtained value.

A signal generating pressure gauge includes a pressure indicating unit having a housing provided with an inlet, a pressure-value indicating panel, a pressure converting unit fluidly communicated with the inlet and provided with a rotary shaft which rotates in response to pressure entering into the inlet, a pointer which rotates with the rotary shaft in order to indicate on the indicating panel the pressure imposed on the inlet, and an electrically conductive pressure control needle movable together with the pointer. An adjustable pressure-setting mechanism includes a rotary plate rotatably mounted in the housing and rotatable relative to the indicating panel, and electrically conductive low-pressure and high-pressure stop units which extend into a setting hole unit in the rotary plate. The positions of the low-pressure and high-pressure stop units in the setting hole unit are adjustable and correspond to the lower and upper limits of a desired pressure range. The stop units limit movement of the pressure control needle therebetween. A signal transmitting unit includes an input voltage cable electrically coupled to the pressure control needle, and low-pressure and high-pressure output signal cables coupled electrically and respectively to the low-pressure and high-pressure stop units.

A pressure gauge includes a housing, a Bourdon tube with a closed end, an adjustment rod mounted rotatably in the housing, a microswitch installed on the adjustment rod, a gear, a sector wheel meshing with the gear, and a crank member interconnecting the sector wheel and the closed end of the Bourdon. Increase of the air pressure inside the Bourdon tube activates a portion of the assembly of the Bourdon tube and the sector wheel to contact the microswitch, so as to stop supply of compressed air from a pressure source to an article which is measured by the gauge. The adjustment rod can be rotated relative to the housing so as to change the distance between the microswitch and the portion of the assembly, thereby adjusting the preset upper limit value of the air pressure inside the Bourdon tube.

A coupling device for a pressure gauge includes an upper positioning plate connected spacedly to a lower positioning plate, a sector gear disposed between the lower and upper positioning plates and mounted rotatably thereto, an adjustment plate mounted adjustably on a top side of the sector gear, a push rod with a first end adapted to be in force-transmitting relationship with an actuating unit of a pressure gauge and a second end connected to the adjustment plate, a pinion meshing with the sector gear and to be mounted with an indicator needle of the pressure gauge thereon, a support plate mounted on a bottom side of the lower positioning plate for supporting distal bottom ends of axles of the sector gear and the pinion thereon, and a spiral spring for biasing the pinion to rotate the indicator needle to a starting position. The bottom side of the lower positioning plate, which is made of plastic, is formed with a plurality of resilient, generally L-shaped hook projections which engage the periphery of the support plate, thus mounting the support plate on the lower positioning plate.

A tire pressure indicator includes an indicator main body having a first end adapted to be connected to an inflating valve member of a tire and a second end which provides a tire pressure reading. A light device has a rotatable support rotatably mounted on an appropriate location of the indicator main body, a light emitting device provided on the rotatable support, and a switch activated control circuit similarly provided on the rotatable support so as to control the operation of the light emitting device. The light device facilitates the connection of the tire pressure indicator to the inflating valve member of a tire and the viewing of the tire pressure reading under poor lighting conditions.
