Inventor: DONARUDO DEYUAN RAISU
IPC: G05D16/06
Filed: 1989-02-27
Abstract: PURPOSE: To make it perform control over pressure and flowing without using any complex link mechanism by directly converting the vertical movement of a cam stem installed at the lower side of a diaphragm to the horizontal movement of a valve disk. CONSTITUTION: A cam stem 26 has two cam surfaces 33 and 34. This cam stem 26 is integrally formed in a cupped relief seat part 30 sealing a diaphragm 20. A disk holder 58 is formed into a round shape at the cross section, while having two cam follow-up surfaces 62 and 63, and it is made slidable in an orifice tube 50 in the horizontal direction. Owing to joint cooperation of those of cam surfaces 33, 34 and cam follow-up surfaces 62, 63, a vertical movement of the cam stem 26 is directly transmitted to a horizontal movement of the valve disk 60 with respect to a valve seat part 52.

Abstract: PURPOSE:To reduce the cost of a slip issuing system by providing a magnetic card reader to each meter to set the meter in a refueling enable state and producing slips by a common printer to issue a slip after reading a card only when a customer wants the slip. CONSTITUTION:The information on a card is read by a meter for refueling when a customer performs refueling, and a password number recorded on the card is fed through a keyboard 24. When the customer wants a slip after refueling carried out by the meter, the card is put into a slip issuing terminal. Then the card is read to issue a slip, and the customer receives this slip. A meter card reader 15 attached to each meter reads the card information and stores the customer code for each meter.

When the coincidence is obtained from said collation, the refueling is possible with the meter. A buffering operation is performed for registration through an SS-POS main body when the refueling of a set amount is through with the meter. Then the amount of refueling, etc. are recorded to an output medium.
