摘要： PURPOSE:To drive an engine for a toy or the like by pressurized gas supply without using a strong inertia force and heighten the output of the engine, by opening a gas feed valve just before the top dead center of a piston. CONSTITUTION:A pin insertion hole 12 is provided in a piston 2 in a cylinder 1 so that the hole extends with a prescribed depth from the center of the top of the piston. A pin 9 is inserted into the hole 12 so that the pin can be moved up and down. A flange-shaped spring stopper 13 is integrally provided on the central part of the pin 9. The spring stopper 13 is located in the large-diameter part 12a of the pin insertion hole 12. The pin 9 is protruded to a prescribed height from the top of the piston 2 by a spring 14. The stiffness of the spring 14 is such that it is compressed by the pressure of pressurized gas supplied through a gas feed valve 4 when the top of the piston 2 is moved up and the top of the pin 9 is brought to a position to open the valve 4. As a result, the gas feed valve 4 is opened just before the top dead center to prevent the pressure of the supplied gas from hindering the upward motion of the piston 2.

摘要： PROBLEM TO BE SOLVED: To improve the quantitative performance of a pump device for mixing two or more types of fluid with each other. SOLUTION: The drive part of a fluid transfer device is formed to demarcate two chambers 104 and 106 by a housing and a piston 98. The two chambers are formed such that a fluid is separated so that the fluid in one chamber does not flow into the other chamber. An inlet port 82 and an outlet port 79 are allowed to communicate with the two chambers. Valve members 116 and 122 are formed to switch the flow of the fluid passing the inlet port and the outlet port. The operation of the valve members is controlled by a release mechanism interlocking with the movement of the piston. A sub system in a post-mix beverage dispenser also uses the fluid driven type proportioning pump. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a compact, simple, lightweight, inexpensive and effective pneumatic motor.
SOLUTION: Each piston is provided with a section having a diameter to form a seal to a corresponding cylinder during the upward cycle of the piston. Compressed fluid entering the corresponding cylinder during the upward cycle pushes the piston upwardly. Each section is further provided with an exhaust groove demarcated thereon so that the seal is broken during the downward cycle of the piston, and the compressed fluid in the cylinder bypasses the piston, and escapes through an air port above each cylinder. The compressed fluid in an intake channel pushes a member to re-seal the cylinder. The upward motion of the piston further generates the inertia force, and the inertia force puts the piston in the downward motion to continue the cycle.

摘要： PURPOSE:To secure positive operation of a valve system, and to improve its reliability by forming an outer surface of a stopper head projecting from a push member, so that its axial profile is a convex curve. CONSTITUTION:A valve system 23 of a valve 32 for supplying gas into a cylinder 22 is composed of a push member 26 and a coil spring 24. The maximum projecting length of the push member 26 from a piston 21 is limited by a stopper head 27. An outer surface 41 of the stopper head 27 is formed so that a profile of its axial section is a convex curve such as a spherical surface. In this way, scuffing or the like is prevented because of smooth contact of the outer surface 41 with the inner surface 42 even if the stopper head 27 is brought into contact with the inner surface 42 of a hollow part 21a in such a state that the push member 26 is offset or inclined owing to an error of the coil spring 24 or some other reasons.

摘要： PURPOSE:To improve an exhaust valve in durability, by constituting the exhaust valve with a spring ring adapted to open and close under the sliding movement of piston, in an engine having a piston contained in a cylinder with an intake port defined through a bottom wall and an exhaust port defined through a bottom peripheral wall. CONSTITUTION:Upon a piston 1 reaching a lower dead point (upper limit), an intake valve 6 closes and an exhaust valve 10 has its ring 10a pulled upwardly by the groove 1a of piston 1 not pressing against a spring ring 10c. In consequence, a sealing material 10f provided at a supporting portion 10g is spaced away from an exhaust port 5 and the exhaust port 5 opens. Then, thr piston 1 lowers downwardly from a lower dead point to an upper dead point and the engagement portion 10b of ring 10a comes into engagement with the end 1b of groove, whereupon the ring 10a is pulled downwardly together with the piston 1. Upon the piston 1 reaching its upper dead point, the intake valve 6 opens and the exhaust valve 10 has its supporting portion 10g of ring 10c pushed by the ring 10a, and thereby closing the exhaust port 5.
